I agree with unlimited atonement if you are walking in the light and our truly sanctified to his will. THe Father took our sins away and nailed them to a cross by his son. God's grace and the precious blood of Christ covers our sins if we are walking in fellowship with him. If we backslide we run the risk of losing our faith because of the temptations of the flesh, the world, and Satan.
2 Corinthians 5:21
God made him who has no sin, sin for us so that through him we might become the righteousness of God.
This is where we disagree because I feel if someone walks away from God and gives up due to the constant pull of the world that they risk the chance of losing their God given gift of Faith and thus give up and go back to the sinful nature as their master and start to have confidence in the flesh again.
Thus
Hebrews 6:4-6
It is impossible for those who have been enlightened, who have tasted the heavenly gift, who have shared in the Holy Spirit, who have tasted the goodness of the word of God and the powers of the coming age, if they fall away, to be brought back to repentance, because to their loss they are crucifying the Son of God all over again and subjecting him to public disgrace.
Thus Calvinists seem to agree that if someone walks away they never had true faith and were impostors. I don't see where someone can come off as to judge someone else's salvation. Plus alot of others feel as if the devil has no way of decieving believers from trusting in themselves and walking away. This scripture says clearly that if someone tasted the good news and love of Jesus and turned their back on him and discredited all of his works as false and returned to the world that it would be impossible for them to repent and come back.
Ezekiel 33:13
If I tell the righteous man he will surely live, but then he trusts in his righteousness and does evil, none of the righteous things he has done will be remembered; he will die for the evil he has done.
This warns against the self-righteous who decide they can go back to their old master of the flesh and put their confidence back in the flesh. Thus they would be turning their back on Jesus and saying I have done enough for the kingdom and I am retiring until death to gratify my fleshly pleasures that I gave up for the past odd years. Plus we know who got kicked out of heaven for being self-righteous and prideful.
I am not a Calvinistic scholar like some but I understand the basic principles. My problem is it seems as if Calvinists try to figure out who has true salvation and who was a false impostor because the temptations of the flesh, the world, and Satan drew them away to where they never answered the call and the devil broke their faith because they didn't grow in their salvation.
1 Peter 2:2
Like newborn babies crave pure spiritual milk so by it you will grow in your salvation now that you have tasted that the Lord is good.
The living word is our foundation for our personal faith after salvation. Some don't read the word and their faith stays weak and the pull of the world keeps alot in spiritual dormancy. We can't grow in our salvation if we don't feed on the word and in essence strengthen our gift of faith. The Holy Spirit is our counselor in the word and alot never ask him to help.
