Like newborn babies, crave pure spiritual milk, so that by it you may grow up in your salvation. 1 Peter 2:2

Instruct a wise man and he will be wiser still; teach a righteous man and he will add to his learning. Proverbs 9:9

Teach us to number our days aright, that we may gain a heart of wisdom. Psalm 90:12

Anyone who lives on milk, being still an infant, is not acquainted with the teaching about righteousness. But solid food is for the mature, who by constant use have trained themselves to distinguish good from evil. Hebrews 5:13-14

Let us leave the elementary teachings about Christ and go on to maturity. Hebrews 6:1

Perseverance must finish its work so that you may be mature and complete, not lacking anything. James 1:4

It was Christ who gave some to be apostles, some to be prophets, some to be evangelists, and some to be pastors and teachers, to prepare God’s people for works of service, so that the body of Christ may be built up until we all reach unity in the faith and in the knowledge of the Son of God and become mature, attaining to the whole measure of the fullness of Christ. Ephesians 4:11-13

God who began a good work in you will carry it on to completion until the day of Christ Jesus. Philippians 1:6
