Looking for the scripture that discusses about how we are born children of perdition and then through baptism we are adopted as children of God.
Could it be this:
Eph. 2 And you he made alive, when you were dead through the trespasses and sins
 in which you once walked, following the course of this world, following the prince of the power of the air, the spirit that is now at work in the sons of disobedience.
 Among these we all once lived in the passions of our flesh, following the desires of body and mind, and so we were by nature children of wrath, like the rest of mankind.
 But God, who is rich in mercy, out of the great love with which he loved us,
 even when we were dead through our trespasses, made us alive together with Christ (by grace you have been saved),
 and raised us up with him, and made us sit with him in the heavenly places in Christ Jesus,
St. Paul doesn’t use the word baptism, but he alludes to it.
That’s it thanks.
You’re welcome. :tiphat: I think it important to note that St. Paul is not saying that humans are totally depraved, but only slaves to depravity because of our fallen nature. In other writings he juxtaposed being slaves to sin to being slaves of Christ–a nice play on words to get his point across.
We humans are wounded in our nature because of the fall, but not totally depraved.
