When toddlers scribble, we look at their handy work and say that it looks so good. As children grow, we expect them to learn to color in the lines. The more they work with their color crayons, they learn to change shades with a crayon. Some people become incredible artist with a box of crayons. Our maturity is seen in how we color with our character.
Philippians 4:8-9 (NIV)
8 Finally, brothers, whatever is true, whatever is noble, whatever is right, whatever is pure, whatever is lovely, whatever is admirable--if anything is excellent or praiseworthy--think about such things.
9 Whatever you have learned or received or heard from me, or seen in me--put it into practice. And the God of peace will be with you.
