18and thank God ◄in all circumstances/regardless of what happens►. God wants you to behave like that because of what Christ Jesus has done for you (OR, because you have a close relationship with Christ Jesus).
18Continually say “Thankyou!” to God. Say like that to him when you are in a good way and when you are in a bad way also. Christians should do like that. God wants that sort of thing.
18in all things do ye thankings. For this is the will of God in Christ Jesus, in all you. (in all things give thanks. For this is the will of God in the Messiah Jesus, for all of you.)
