God gives to every man a measure of faith. See Romans 12:3. Why does God do this? God gives to every man a measure of faith to believe in His Only Son, Jesus Christ. This is the purpose God gives to every man a measure of faith.
This is a common argument that is weak at best to be honest. Really look at what you are claiming here. You are saying that every single man on Earth has been allotted faith. You call it a measure of faith but it would have to be faith nonetheless. Considering Ephesians 2:8 says we are saved through faith by the grace of God, this would mean every person on Earth would be saved due to the faith they have all been given. Not only this but the notion that God gives every man on Earth faith is:
a) completely out of context
b) not supported by the surrounding verses
c) not even supported by historical Arminianism
The context of Romans 12 clearly shows that Paul is writing to fellow believers. This is evident by his usage of the word bretheren (v.1). Not only this but he also tells us to prove what the will of God is. We know this will of God is for His Elect to be reconciled to Him. Like the word or not, it is a word used in Scripture and there is no denying this fact. One must either embrace it or dance around it but they can never deny it. Everything in Romans 12 refers to believers so there is no reason to believe verse 3 is any different...especially when the rest of that same verse is about believers only. This means the accurate context is that God has allotted a measure of faith to each believer.
If you really wanted to go historical, you could try claiming that God has given each man a measure of grace. This is the point Jacobus Arminius made. He believed man was totally depraved and incapable of choosing God in his own free will. However, he believed that God then gave prevenient grace to everybody on Earth for all time so that they could then choose Him. He felt that, without this prevenient grace, man could never choose Him but, with it, man was now capable of performing such an act. He never taught universal measure of delivered faith but rather, that of prevenient grace. However, the concept of prevenient grace is not taught in Scripture. Arminians use verses such as Romans 12:3 and replace faith with grace to make their point but grace and faith are clearly 2 distinctly separate things.
Again, your stance is out of context, out of historical teaching (for your own belief system nonetheless), and is not supported by the verses within the chapter.
God has also given to every man something else as well. God has also given mankind freewill. So, Man with the measure of faith from God and his freewill has the choice now to receive Jesus Christ or not after hearing the Gospel.
If God gave each man faith, each man would have a level of belief. Yet, Scripture declares man to be incapable of understanding the things that are Spiritually discerned (1 Corinthians 2:14). However, it does say man can have a head knowledge type of belief because even the angels have this and they shudder. However, belief is not the same as faith. The word faith is used in Scripture when referring to salvation or belief in the Gospel; not general belief or an ability to believe. Look for it. You won't find it.
If after hearing the Saving Gospel of Jesus Christ, A man chooses to not accept the Gift of Salvation provided by Jesus Christ, then, God says that this man is condemned for not believing on His Only Son, Jesus Christ. John 3:18b.
Actually, it says he is already condemned but that is a whole different can of worms.
Suffice it to say, God's Election is conditional. The Condition of God's Election is a person's choice to follow Jesus Christ. Once a person chooses to follow Jesus Christ, then, this person becomes a member of one of the following Seeds in the Seed Covenant of Abraham in the New Testament...
I'll give you a few "pieces of fat" to chew on regarding unconditional election:

This looks pretty unconditional to me. According to this, man has no say whatsoever. It really all depends on whether or not the Son chooses to reveal the Father. You may say that the Son chooses to reveal the Father to everybody yet...

predestined, He also called;
God's Election came before His calling. He elected unconditionally, the Son chooses to reveal the Father unconditionally, and those who are called are eternally in the Will of the Father so that all things work together for good to those who love Him...His Elect.
If election was conditional, nobody would have been elected because nobody would have been revealed by the Son. Scripture is clear that there are 2 groups; those revealed and those not revealed. This means those not revealed will never know the Father. The only existing condition was the condition of whether or not the Son revealed the Father and he only did this to the Elect of God.

If a man, woman, or child is Jewish who choose to follow Jesus Christ as Messiah, They are called into the Seed of Isaac multiplied as the stars of the heaven. Genesis 21:12, Romans 9:7, and Hebrews 11:18. They become Saints.
If a man, woman, or child is Gentile who choose to follow Jesus Christ, they are called into the Seed of Abraham multiplied as the stars of the heaven. Romans 10:9-10, Acts 15:14, and Ephesians 2:8-9. They become Christian.
Saints and Christians are synonymous (Romans 1:7).
Now, This part of the writing...You say..."He always will choose God once this occurred!"
No, Man will not always choose God. Because, Once God makes the offer of Salvation and this offer is rejected, then, God sends a strong delusion so that everyone who rejects Salvation will believe a lie. 2 Thessalonians 2:11.
Many are called but few are chosen. The reason few will believe is because they are not all chosen, have not all been revealed the Father by the Son, and cannot all understand the things of the Spirit because they do not have the Spirit.
The Bottom line is simply this. A person has a freewill to choose to Love the Truth or Choose to not love the Truth. Once a person makes their choice to reject the Love of the Truth, God will turn them over to a reprobate mind for a Christian, see Romans 1:28, and or an apostate, see Hebrews 4:6, if they are a Saint.
Your claim of this goes against one's nature. The unregenerate man is free to not love God but he is not free to love God. The freedom is not limited by God. God is not forcing this man to stay away. However, God is not calling him unto Himself either. This man is choosing to stay away out of his own free will because his nature does not desire the things of God. This is why, though not having the ability to choose God, he is still held accountable. He is willingly rejecting God with every fiber of his body. God is sovereign in all things yet man is still responsible for his actions that he partakes in gladly.
