And walk in love, as Christ also has loved us and given Himself for us, an offering and a sacrifice to God for a sweet-smelling aroma. But fornication and all uncleanness or covetousness, let it not even be named among you, as is fitting for saints; neither filthiness, nor foolish talking, nor coarse jesting, which are not fitting, but rather giving of thanks. Ephesians 5:2-4
Walk: to regulate one's life, to conduct oneself
Love: which centers in moral preference, typically refers to divine love (= what God prefers)
Sweet-smelling aroma: fragrance, perfume
Fornication: from the Greek "porneuo"; harlotry (including adultery and incest)
Uncleanness: impurity (the quality), physically or morally
Covetousness: greedy desire to have more
Not even: not once, so much as
Be named: of things which are called by their own name because they are present or exist
Fitting: to be suitable or proper
Filthiness: dishonor, shamefulness, obscenity
Foolish talking: silly talk, buffoonery
Course jesting: grossly or obscenely abusive, vulgar or indecent in speech, abusive
Not fitting: unbecoming, discreditable
But: a strong adversative conjunction – but instead
Rather: comparative adverb so it refers to what is better as compared to what is merely "good." This involves prioritizing or ranking to elevate the better over the good, i.e. the higher priority (the more important)
Giving of thanks: gratitude; actively, grateful language (to God, as an act of worship)
Nicknames are often given based on what we do, or some characteristic we have. What name is associated with you? Is it proper and suitable—for a Christian to have? Does the nickname represent Christ in a good way?
Ephesians 5:3, 4 give a list of areas to avoid for they are discreditable in view of Christianity. Partaking in those things tarnishes your reputation and creates a pungent odor to God.
BUT rather—Don't even begin to think about those pungent things, instead choose the BEST! And what is that BETTER thing to choose? Actively giving thanks to God! When we are actively involved in Thanks Living, our desire will be to choose the BEST!
