Since the prayer of the wicked is an abomination to God (Proverbs 15:8), then for the wicked to pray would be an abomination to God.
Only those who believe that the work of Jesus Christ alone makes the difference between salvation and damnation are ones whose prayers are acceptable to God. That means that all the prayers of those who believe that Jesus Christ died for everyone without exception are abominations to God:
==For You are not a God enjoying wickedness; nor shall evil live with You. The boasters shall not set themselves before Your eyes. You hate all workers of iniquity (Psalm 5:4-5)==
God hates boastERS. So what is a boaster? The Hebrew word comes from “ha-LAL”, which means “to shine” or “to glory.” A boaster is a “shiner,” or “one who makes a show.” He is a “glorier,” or one who glories in himself. He is one who boasts in his own strength. He boasts of his own righteousness as forming some or all of the ground of his salvation. He boasts of his reforming and abstaining and obeying as that which recommends him to God. He glories in his own works as that which make the difference between him and the unsaved. Do you want to know how to find out what a person glories in? You just have to find out what he thinks makes the ultimate difference between heaven and hell.
Now if you go up to a religionist who calls himself a Christian and ask him what makes the ultimate difference between heaven and hell, what’s he going to say? Of course, he’s going to say, “Jesus Christ.” But this is just a deceptive cloak.
What you really need to ask him is if Jesus Christ died for everyone without exception. If he says “yes,” then you KNOW wherein he glories. He believes that Jesus Christ died for those in heaven and those in hell. Thus, he believes that it is NOT the work of Jesus Christ ALONE that makes the ultimate difference between heaven and hell; instead, he believes that it is the work of the SINNER that makes the ultimate difference between heaven and hell. Thus, he boasts in, he glories in, the work of the SINNER.
And since he thinks he’s saved, he is glorying in HIS OWN WORKS as what makes him to differ between himself and other sinners. He believes that it is his FAITH or his REPENTANCE or his PERSEVERANCE or his GOOD DEEDS that make the difference. He is a boaster, and God hates him. Let me make it very clear: GOD HATES all who believe that Jesus Christ died for everyone without exception.
In contrast to those who boast in or glory in themselves, true Christians are ones who boast in or glory in the cross of Christ:
==But may it never be for me to boast, except in the cross of our Lord Jesus Christ, through whom the world has been crucified to me, and I to the world (Galatians 6:14)==
The CROSS OF CHRIST is the only thing true Christians glory in! They glory in the cross because they KNOW that it is what makes the ONLY difference between heaven and hell! They KNOW that the cross of Christ demands and ensures the salvation of EVERY SINGLE PERSON WITHOUT EXCEPTION for whom Christ died! They know that ALL those for whom Christ died on the cross WILL BE SAVED. They know that the cross of Christ is the ONLY ground of our salvation! Thus, they glory (i.e., boast in) in the cross.
