Mature

A. 1CORINTHIANS 3:1-4

And I, brethren, could not speak to you as to spiritual men, but as to men of flesh, as to infants in Christ. I gave you milk to drink, not solid food; for you were not yet able to receive it. Indeed, even now you are not yet able, for you are still fleshly. For since there is jealousy and strife among you, are you not fleshly, and are you not walking like mere men?

B. HEBREWS 5:13-14

For everyone who partakes only of milk is not accustomed to the word of righteousness, for he is an infant. But solid food is for the mature, who because of practice have their senses trained to discern good and evil.

C. EPHESIANS 4:13-14

Until we all attain to the unity of the faith, and of the knowledge of the Son of God, to a mature man, to the measure of the stature, which belongs to the fullness of Christ. As a result, we are no longer to be children, tossed here and there by waves and carried about by every wind of doctrine, by the trickery of men, by craftiness in deceitful scheming;

D. 1CORINTHIANS 14:20

Brethren, do not be children in your thinking; yet in evil be infants, but in your thinking be mature.

 And do not be conformed to this world, but be transformed by the renewing of your mind, so that you may prove what the will of God is, that which is good and acceptable and perfect.
