“Set your affection on things above, not on things on the earth. For ye are dead, and your life is hid with Christ in God” (Colossians 3:2–3).
Being alive on this earth does not mean that we have life: this is only a lifetime.
“For since by man came death, by man came also the resurrection of the dead. For as in Adam all die, even so in Christ shall all be made alive” (1 Corinthians 15:21–22).
