No one can escape coming into the world as a baby because that is the only way to get here...But it is tragic when a baby fails to mature.

God has the same desire for us as His children, That is why He calls to us,
"Go on to maturity!".
Hebrews 6:1 Therefore leaving the elementary teaching about the Christ, let us press on to maturity, not laying again a foundation of repentance from dead works and of faith toward God...
