Isaiah 25:8 He will swallow up death forever. The Sovereign LORD will wipe away the tears from all faces; he will remove the disgrace of his people from all the earth. The LORD has spoken.
1 Corinthians 15:54-57
54 When the perishable has been clothed with the imperishable, and the mortal with immortality, then the saying that is written will come true: “Death has been swallowed up in victory.”
55 “Where, O death, is your victory? Where, O death, is your sting?”
56 The sting of death is sin, and the power of sin is the law.
57 But thanks be to God! He gives us the victory through our Lord Jesus Christ.
Psalm 23:4 Even though I walk through the valley of the shadow of death, I will fear no evil, for you are with me; your rod and your staff, they comfort me.
