Concerning the dead in the Lord, Paul advises us

Paul advises us not to grieve about the dead in the Lord as others who have no hope, implying that we can have hope in the resurrection of the dead and the eternal life that follows. Therefore, we should not worry excessively about them, but rather be comforted by the hope we have in Christ. Additionally, there is no mention of praying for the repose of their souls or being merry in this context. While it is appropriate to give thanks to God for our lives, this is not specifically mentioned in relation to the dead in the Lord.
