1 THEREFORE BE imitators of God [copy Him and follow His example], as well-beloved children [imitate their father].2 And walk in love, [esteeming and delighting in one another] as Christ loved us and gave Himself up for us, a slain offering and sacrifice to God [for you, so that it became] a sweet fragrance. 3 But immorality (sexual vice) and all impurity [of lustful, rich, wasteful living] or greediness must not even be named among you, as is fitting and proper among saints (God’s consecrated people).4 Let there be no filthiness (obscenity, indecency) nor foolish and sinful (silly and corrupt) talk, nor coarse jesting, which are not fitting or becoming; but instead voice your thankfulness [to God].
V1 We imitate God just as small children imitate their parents. We are as children to God. We have a similar view of God that our small children have of us. They want to be like us, and they act and do/say the things that we do. We do that towards God, but there is a difference. We cannot physically see God as our children can see us. So how will we imitate something that we cannot physically see?
To imitate God, we must know as much about Him as we can. We can learn this through the bible. His word gives us insight into who He is, who His Son is, and who the Holy Spirit is. We must seek Him through our daily time set aside with Him just to give Him our ears and hearts.
V2 Walk in love as Christ loved us and died for us. There it is again. Paul mentions that we are to love others as Christ loved us. The repetition Paul puts on loving others raises the importance of it. How can we be followers of God if we are not loving others? God is all about loving others, and we should reflect that in our daily lives.
V3 Sexual sin, lust and greediness must not even be named among you. This is the reason why porn is so terrible for Christians. It should not even be named among you. Followers of God should not even have these sins related to them. It makes complete sense, but SO MANY Christians are involved with lust. It is a secret sin, not discussed among them. I believe Satan has a major grip on Christians today in this area.
V4 Let there be no obscenity or indecency, or foolish, silly, corrupt talk be named among you. Instead, voice your thankfulness to God. This continues to describe the behavior of Christians. To me, this covers joking or gossip or anything that does not uplift the listener.
