I don't play any blame game.
Yes I did, you didn't answer.
No baby is "pure". No one "turns" into a sinner, the sinner that's already in them manifests as they age.
There is no infantile purity, there's your own fantasy. "Infantile purity" is not even scientific as infants inherit mother's microbiome from the birth canal.
Evil comes from the heart.
Yet they subsist and remain until Christ returns.
No you don't. That's your own sin of pride.
Ask yourself first, what idol is preventing you from understanding these below?
What then? Are we better than they? Not at all. For we have previously charged both Jews and Greeks that they are all under sin. (Rom. 3:9)
Now we, brethren, as Isaac was, are children of promise. But, as he who was born according to the flesh then persecuted him who was born according to the Spirit, even so it is now. (Gal. 4:28-29)
If we say that we have no sin, we deceive ourselves, and the truth is not in us. If we confess our sins, He is faithful and just to forgive us our sins and to cleanse us from all unrighteousness. If we say that we have not sinned, we make Him a liar, and His word is not in us. (1 Jn. 1:8-9)
No, you fantasize and fabricate.
You wouldn't have been acting like the prideful Pharisee if his kingdom were in your heart. You have no humility.
Nonetheless you erroneously sought Jesus as an escape, which is contrary to his own expectation in his prayer.
