'Perfect' in the Bible

You, therefore, will be perfect [growing into spiritual maturity both in mind and character, actively integrating godly values into your daily life], as your heavenly Father is perfect.

If you then, evil (sinful by nature) as you are, know how to give good and advantageous gifts to your children, how much more will your Father who is in heaven [perfect as He is] give what is good and advantageous to those who keep on asking Him.

He said to them, “Why are you afraid, you men of little faith?” Then He got up and rebuked the winds and the sea, and there was [at once] a great and wonderful calm [a perfect peacefulness].

Jesus answered him, “If you wish to be perfect [that is, have the spiritual maturity that accompanies godly character with no moral or ethical deficiencies], go and sell what you have and give [the money] to the poor, and you will have treasure in heaven; and come, follow Me [becoming My disciple, believing and trusting in Me and walking the same path of life that I walk].”

and they said to Him, “Do You hear what these children are saying?” And Jesus replied to them, “Yes; have you never read [in the Scripture], ‘Out of the mouths of infants and nursing babies You have prepared and provided praise for Yourself’?”
