In the Old Testament or Torah

God revealed Himself as 

Hear, O Israel: The Lord our God is one Lord: –   Deuteronomy 6:4

¹³ And Moses said unto God, Behold, when I come unto the children of Israel, and shall say unto them, The God of your fathers hath sent me unto you; and they shall say to me, What is his name? what shall I say unto them?

¹⁴ And God said unto Moses, I Am That I Am: and he said, Thus shalt thou say unto the children of Israel, I Am hath sent me unto you. – Exodus 3

⁶ Thus saith the Lord the King of Israel, and his redeemer the Lord of hosts; I am the first, and I am the last; and beside me there is no God. – Isaiah 44:5

⁵ I am the Lord, and there is none else, there is no God beside me: I girded thee, though thou hast not known me:

⁶ That they may know from the rising of the sun, and from the west, that there is none beside me. I am the Lord, and there is none else.

⁷ I form the light, and create darkness: I make peace, and create evil: I the Lord do all these things.

⁸ Drop down, ye heavens, from above, and let the skies pour down righteousness: let the earth open, and let them bring forth salvation, and let righteousness spring up together; I the Lord have created it.

⁹ Woe unto him that striveth with his Maker! Let the potsherd strive with the potsherds of the earth. Shall the clay say to him that fashioneth it, What makest thou? or thy work, He hath no hands?

¹⁰ Woe unto him that saith unto his father, What begettest thou? or to the woman, What hast thou brought forth?

¹² I have made the earth, and created man upon it: I, even my hands, have stretched out the heavens, and all their host have I commanded.

 

Through out the Old Testament and similarly in Jewish Torah and Tanakh (Hebrew Bible), God reveals Himself as one and there is none beside Him.

There is no doubt there is only ONE GOD – The true living God.

 

In the new testament its described about Jesus ,

1 In the beginning was the Word, and the Word was with God, and the Word was God.

² The same was in the beginning with God.

³ All things were made by him; and without him was not any thing made that was made.

⁴ In him was life; and the life was the light of men.

¹⁴ And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth.

¹⁷ For the law was given by Moses, but grace and truth came by Jesus Christ.

¹⁸ No man hath seen God at any time, the only begotten Son, which is in the bosom of the Father, he hath declared him.

John 8

⁵⁷ Then said the Jews unto him, Thou art not yet fifty years old, and hast thou seen Abraham?

⁵⁸ Jesus said unto them, Verily, verily, I say unto you, Before Abraham was, I am.

John 10

²⁴ Then came the Jews round about him, and said unto him, How long dost thou make us to doubt? If thou be the Christ, tell us plainly.

²⁵ Jesus answered them, I told you, and ye believed not: the works that I do in my Father’s name, they bear witness of me.

²⁶ But ye believe not, because ye are not of my sheep, as I said unto you.

²⁷ My sheep hear my voice, and I know them, and they follow me:

²⁸ And I give unto them eternal life; and they shall never perish, neither shall any man pluck them out of my hand.

²⁹ My Father, which gave them me, is greater than all; and no man is able to pluck them out of my Father’s hand.

³⁰ I and my Father are one.

³¹ Then the Jews took up stones again to stone him.

³² Jesus answered them, Many good works have I shewed you from my Father; for which of those works do ye stone me?

³³ The Jews answered him, saying, For a good work we stone thee not; but for blasphemy; and because that thou, being a man, makest thyself God.

³⁴ Jesus answered them, Is it not written in your law, I said, Ye are gods?

³⁵ If he called them gods, unto whom the word of God came, and the scripture cannot be broken;

³⁶ Say ye of him, whom the Father hath sanctified, and sent into the world, Thou blasphemest; because I said, I am the Son of God?

³⁷ If I do not the works of my Father, believe me not.

³⁸ But if I do, though ye believe not me, believe the works: that ye may know, and believe, that the Father is in me, and I in him.

⁶ Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me.

⁷ If ye had known me, ye should have known my Father also: and from henceforth ye know him, and have seen him.

⁸ Philip saith unto him, Lord, show us the Father, and it sufficeth us.

⁹ Jesus saith unto him, Have I been so long time with you, and yet hast thou not known me, Philip? he that hath seen me hath seen the Father; and how sayest thou then, Show us the Father?

¹⁰ Believest thou not that I am in the Father, and the Father in me? the words that I speak unto you I speak not of myself: but the Father that dwelleth in me, he doeth the works.

¹¹ Believe me that I am in the Father, and the Father in me: or else believe me for the very works’ sake.

2 John

⁹ Whosoever transgresseth, and abideth not in the doctrine of Christ, hath not God. He that abideth in the doctrine of Christ, he hath both the Father and the Son.

²² For the Father judgeth no man, but hath committed all judgment unto the Son:

²³ That all men should honour the Son, even as they honour the Father. He that honoureth not the Son honoureth not the Father which hath sent him.

²⁴ Verily, verily, I say unto you, He that heareth my word, and believeth on him that sent me, hath everlasting life, and shall not come into condemnation; but is passed from death unto life.

There is only One God – One being in Three persons – The Father , The Son Jesus Christ and The Holy Spirit.

Three persons, but one God.

Can a man at the same time be a Son, a Father and a Husband?

A man is the Son of his mother.

The same man is a husband to his wife.

The same man is a father to his child.

But He is still the same person, but three different roles. -> We can understand this applicable for human beings.

As of God, HE is infinitely superior than human beings. He is our Creator. He is one being and existing in three distinct persons – The Heavenly Father, the Son and The Holy Spirit.

1 John 5

⁷ For there are three that bear record in heaven, the Father, the Word, and the Holy Ghost: and these three are one.

 

Christians do not have Three Gods, but only one God – who is one Being which exist in three distinct persons. The Heavenly Father, the Son and The Holy Spirit are One.

The Christian world seem to be divided on the doctrines supported by Arminianism and Calvinism.

Its mostly on the topic of how is a Christian born again. Either by free will of human or by the direct working of God?

The Bible says – John 6:44 ⁴⁴ No man can come to me, except the Father which hath sent me draw him: and I will raise him up at the last day.

The Bible also says – Acts 2: 

³⁷ Now when they heard this, they were pricked in their heart, and said unto Peter and to the rest of the apostles, Men and brethren, what shall we do?

³⁸ Then Peter said unto them, Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost.

³⁹ For the promise is unto you, and to your children, and to all that are afar off, even as many as the Lord our God shall call.

⁴⁷ Praising God, and having favour with all the people. And the Lord added to the church daily such as should be saved.

 

Acts 13:48 ⁴⁸ And when the Gentiles heard this, they were glad, and glorified the word of the Lord: and as many as were ordained to eternal life believed.

 

ROMANS 9

¹⁰ And not only this; but when Rebecca also had conceived by one, even by our father Isaac;

¹¹ (For the children being not yet born, neither having done any good or evil, that the purpose of God according to election might stand, not of works, but of him that calleth;)

¹² It was said unto her, The elder shall serve the younger.

¹³ As it is written, Jacob have I loved, but Esau have I hated.

¹⁴ What shall we say then? Is there unrighteousness with God? God forbid.

¹⁵ For he saith to Moses, I will have mercy on whom I will have mercy, and I will have compassion on whom I will have compassion.

¹⁶ So then it is not of him that willeth, nor of him that runneth, but of God that sheweth mercy.

¹⁷ For the scripture saith unto Pharaoh, Even for this same purpose have I raised thee up, that I might shew my power in thee, and that my name might be declared throughout all the earth.

¹⁸ Therefore hath he mercy on whom he will have mercy, and whom he will he hardeneth.

¹⁹ Thou wilt say then unto me, Why doth he yet find fault? For who hath resisted his will?

²⁰ Nay but, O man, who art thou that repliest against God? Shall the thing formed say to him that formed it, Why hast thou made me thus?

²¹ Hath not the potter power over the clay, of the same lump to make one vessel unto honour, and another unto dishonour?

²² What if God, willing to shew his wrath, and to make his power known, endured with much longsuffering the vessels of wrath fitted to destruction:

²³ And that he might make known the riches of his glory on the vessels of mercy, which he had afore prepared unto glory,

²⁴ Even us, whom he hath called, not of the Jews only, but also of the Gentiles?

 

God is sovereign, and there is human responsibility also. The Lord commanded His disciples to preach the gospel. 

So it is the disciple’s responsibility to preach the gospel as the Spirit of God leads. 

It is the Holy Spirit who convicts the world of sin and draws the sinner to the Saviour. 

John 16:8 ⁸ And when he is come, he will reprove the world of sin, and of righteousness, and of judgment:

Only a sinner requires a Saviour. To make a man/woman to realise that they are a sinner, is the Spirit’s work. With the Spirit’s illumination, the sinner recognises the wretched state they are in, and realise they definitely need a Saviour who alone can help them out. No one can save them  by themselves. They repent of their sins and accept the Lord’s free gift of salvation. 

So is it Arminianism or Calvinism? DOES IT MATTER?

Do what the Lord clearly says us to do – Preach the gospel as the Lord leads and then let the Spirit of God work and let the people get saved.

Arguing and debating on Arminianism or Calvinism does it help us to draw closer to the Lord? Can we please channelise this energy and time to know the Lord better and do the work which He wants us to do. Lets not give chance for Satan to mock at the internal Christian arguments. Lets make sure we focus on the weightier matters as well. 

Matthew 23:23

²³ Woe unto you, scribes and Pharisees, hypocrites! for ye pay tithe of mint and anise and cummin, and have omitted the weightier matters of the law, judgment, mercy, and faith: these ought ye to have done, and not to leave the other undone.

1 Timothy 1:4

which minister questions, rather than godly edifying which is in faith: so do.

⁵ Now the end of the commandment is charity out of a pure heart, and of a good conscience, and of faith unfeigned:

Titus 3:9 ⁹ But avoid foolish questions, and genealogies, and contentions, and strivings about the law; for they are unprofitable and vain.

JUDE

³ Beloved, when I gave all diligence to write unto you of the common salvation, it was needful for me to write unto you, and exhort you that ye should earnestly contend for the faith which was once delivered unto the saints.

⁴ For there are certain men crept in unawares, who were before of old ordained to this condemnation, ungodly men, turning the grace of our God into lasciviousness, and denying the only Lord God, and our Lord Jesus Christ.

 

But definitely defend if there arises a question of whether Christ is the Saviour or any opposition arises against the gospel. If its only a question of small matters, let us focus on  loving the Lord Jesus with all our heart and keeping His commandments. Let’s keep this question (whether Arminianism or Calvinism is right )to ask Him when we meet Him in heaven. JESUS is the Lord.
