1 Thessalonians 5:16-18 AMPC
Be happy [in your faith] and rejoice and be glad-hearted continually (always);
Be unceasing in prayer [praying perseveringly];
Thank [God] in everything [no matter what the circumstances may be, be thankful and give thanks], for this is the will of God for you [who are] in Christ Jesus [the Revealer and Mediator of that will].
