Psalm 58 simply afforms that all men are conceived in a state of wickedness. It does not say that all men remain there. Some are Saved.
This "Some" may include all those whom God permits to die in infancy -- at least, the greatest Calvinist theologians have preached that God has Elected to Save all those whom He has permitted to die in infancy, whereas the greatest Arminian/Free-Will theologians have preached that God has ordained to Damn To Hell ALL Infants who die unbaptized.
Psalm 58 says no such thing.
You may try to reach that conclusion from other scripture but 58 says “the wicked”.
If all were wicked, then what would be the point of specifying “the wicked”?
>whereas the greatest Arminian/Free-Will theologians have preached that God has ordained to Damn To Hell ALL Infants who die unbaptized.
You know I seem to have misplaced the reference in my Bible where it says “For by Baptism ye have been saved...” could you give that to me?
