Does anyone have evidence that there is a life after death?
Jesus declared that the thief being crucified alongside him would be in paradise that day after he died…All it took was him declaring his revelation and faith faith that Jesus in the way to eternity.So yes there is evidence that you will live again
Jesus raised Lazarus. Then, He rose himself from the grave. He provides the same for those who trust in Him.
Being at peace after someone dies, may be a sign from God saying its okay to morn and get upset at loosing someone, but that person wouldn’t want morned for forever God knows the pain each person goes through.
