The end of Genesis is filled with instances of humans worrying and with God reassuring. There are to promises that God specifically makes to His people that He is Sovereign and that He is present. When we know Him, He is the place for us to take our worry and insecurities.
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]
