Therefore if any man be in Christ, he is a new creation: old things are passed away; behold all things are become new.” So then, we are to be forgetting what is behind and straining toward what is ahead, pressing toward the goal to win the prize for which God has called us heavenward in Christ Jesus. For when we were children we thought as children do, we reasoned after that manner. Now that we are more matured, we are to put the ways of childhood behind us. Ephesians 4 teaches us how that looks in our daily living.
