When I was a child, I talked like a child, I thought like a child, I reasoned like a child. When I became a man, I put the ways of childhood behind me. 1 Corinthians 13:11

Do not conform to the pattern of this world, but be transformed by the renewing of your mind. Then you will be able to test and approve what God’s will is—his good, pleasing and perfect will. Romans 12:2

And this is my prayer: that your love may abound more and more in knowledge and depth of insight, so that you may be able to discern what is best and may be pure and blameless for the day of Christ, filled with the fruit of righteousness that comes through Jesus Christ—to the glory and praise of God. Philippians 1:9-11

 …so that you may live a life worthy of the Lord and please him in every way: bearing fruit in every good work, growing in the knowledge of God… Colossians 1:10

Brothers and sisters, I do not consider myself yet to have taken hold of it. But one thing I do: Forgetting what is behind and straining toward what is ahead, I press on toward the goal to win the prize for which God has called me heavenward in Christ Jesus. Philippians 3:13-14

…being confident of this, that He who began a good work in you will carry it on to completion until the day of Christ Jesus. Philippians 1:6

I am the vine; you are the branches. If you remain in me and I in you, you will bear much fruit; apart from me you can do nothing. John 15:5

Let your roots grow down into him, and let your lives be built on him. Then your faith will grow strong in the truth you were taught, and you will overflow with thankfulness. Colossians 2:7

Therefore, rid yourselves of all malice and all deceit, hypocrisy, envy, and slander of every kind. Like newborn babies, crave pure spiritual milk, so that by it you may grow up in your salvation, now that you have tasted that the Lord is good. 1 Peter 2:1-3

Be diligent in these matters; give yourself wholly to them, so that everyone may see your progress. 1 Timothy 4:15
