Paul gives us a recap of why we shouldn't be ashamed of the Gospel; a view of why this God of ours is the one who has always made a way for us when we could not; and why we often need to adjust our viewpoint so that we'd understand that our God is bigger than our grasp or understanding.
So roll up your sleeves, put your mind in gear, be totally ready to receive the gift that’s coming when Jesus arrives. Don’t lazily slip back into those old grooves of evil, doing just what you feel like doing. You didn’t know any better then; you do now. As obedient children, let yourselves be pulled into a way of life shaped by God’s life, a life energetic and blazing with holiness. God said, “I am holy; you be holy. [1 Peter 1:13-16]
