Jesus says: “I am the resurrection, and the life: he that believeth in me, though he were dead, yet shall he live. And whosoever liveth and believeth in me shall never die. Believest thou this?” (John 11:25-27).
“Now if any man have not the Spirit of Christ, he is none of his. And if Christ be in you, the body is dead because of sin; but the Spirit is life because of righteousness. But if the Spirit of him that raised up Jesus from the dead dwell in you, he that raised up Christ from the dead shall also quicken your mortal bodies by his Spirit that dwelleth in you” (Romans 8:5-11).
