'Perfectly' in the Bible

It is he who will go as a forerunner before Him in the spirit and power of Elijah, to turn the hearts of the fathers back to the children, and the disobedient to the attitude of the righteous [which is to seek and submit to the will of God]—in order to make ready a people [perfectly] prepared [spiritually and morally] for the Lord.”

A certain ruler asked Him, “Good Teacher [You who are essentially and morally good], what shall I do to inherit eternal life [that is, eternal salvation in the Messiah’s kingdom]?”

Jesus said to him, “Why do you call Me good? No one is [essentially and morally] good except God alone.
