I see calvinism is in full swing over in this thread.
The facts are that God wants all to be saved, God's grace has appeared unto all men TEACHING to deny ungodliness and worldly lusts, Jesus tasted death for every man, the world, all, and we should pray for all people, God commands all to repent, the true light gives light to every man that comes into the world.
And contrary to what ForestgreenCook just stated, we are not given the Holy Spirit PRIOR to belief. This is in contradiction to Ephesians 1:13.
Nobody in the NT got the Spirit before they believed, like in Pentecost or with the Ephesians or with Cornelius.
1 Corinthians 2 is talking about the deep things of God, as is clear from the earlier verses. Not about understanding the simple message of the Gospel. Here is how people gain faith: Faith cometh by HEARING and hearing by the word of God. You hear the Gospel, you believe the Gospel, you are saved, simple.
You cant just pick up a bible and come out a calvinist as I said before on this forum, it cant happen. Limited atonement especially is so contrary to the NT that you have to read it into the text, force it upon it. And even that isnt enough, you have to make philosophical arguments about "Well does God really save or make saveable" and other falsehoods, when the truth is God does both.
EDIT: I noticed you also said we are justified BEFORE we believe? That is also contrary to scripture:
Galatians 3:24 Therefore the Law has become our tutor to lead us to Christ, so that we may be justified by faith.
This is repeated many times ALL OVER the NT.
Romans 5:1
Therefore, having been justified by faith, we have peace with God through our Lord Jesus Christ,
