Probably the most reassuring words for Christians regarding death, is found in John 11, where Jesus raises Lazarus from the dead. Verse 25 and 26 says: "I am the resurrection and the life, he who believes in Me, even though he dies like everyone else, shall live again, and whoever lives and believes in me shall never die". How wonderful to know that in life hereafter, we who believe in Jesus Christ as our Saviour, will be together.
Paul uses other words to say almost the same: 1 Corinthians 15: 54-55: "Death is swallowed up in vicctory... Death where is your sting? " HALLELUJAH!
