‘And do not be conformed to this world’ means we must not be shaped or molded into the pattern of the world. When you are shaped into the pattern of the world, you will eventually look like the world and the ways of the world rub off on you.The pattern of this world is ungodly. The devil who is the ‘god’ of this world has created an ungodly atmosphere that leads people to sin. His aim in creating such an ungodly atmosphere is to make people follow such unholy patterns leading to sin.You can never get God’s best when you conform to this world because you will always settle for less compared to what God has prepared for you (I Corinthians 2:9-10).As Christians, we must be sensitive to the atmosphere around us recognizing who we are in Christ, have love for God, and reject the ungodly lifestyle the devil might want to force on us daily.If you conform to the standard of the world, you will not experience God’s will and desires for your life. For the things of this world are temporary.We can change our characters by living as a child of light that we are because we are sealed with the Holy Spirit of promise at redemption (Ephesians 1:13) “In whom ye also trusted, after that ye heard the word of truth, the gospel of your salvation: in whom also after that ye believed, ye were sealed with that holy Spirit of promise,”.
