When a person sins then he dies spiritually:
"What fruit had ye then in those things whereof ye are now ashamed? for the end of those things is death...For the wages of sin is death; but the gift of God is eternal life through Jesus Christ our Lord" (Ro.6:21,23).
Since a person dies spiritually when he sins that means he must be alive spiritually before he sins. And in the preceding chapter Paul makes it plain that "all men" die spiritually when they sin:
"Wherefore, as by one man sin entered into the world, and death by sin; and so death passed upon all men, for that all have sinned" (Ro.5:12).
Since "all men" die spiritually as a result of their own sin then that means "all men" are alive spiritually before they sin. That can only mean that all men emerge from the womb spiritually alive.
