John 11
²⁵ Jesus said to her, I am the resurrection, and the life: he that believes in me, though he were dead, yet shall he live:
²⁶ And whoever lives and believes in me shall never die. Believe you this?
Jesus is resurrection and life when Jesus come to your life you will have life. Because Jesus him self he is the resurrection and life. When we belief in him we will get eternal life through him. Starting from the moment we believed the resurrection power of Christ starts to live in us. This power make us alive with christ. This power has resurrected us with Christ. Our dead spirit has become alive. This is our spiritual resurrection which we die with Christ and we resurrected with new spirit we become born again through spirit.
Jesus has the authority to resurrect both physical body. But Jesus wants us to know that he is resurrection and life he can resurrect dead body and he can resurrect dead spirit and who ever believes in him will never die, they will leave eternally with Jesus, they are still alive in spirit even if they are absent physically. So any body who believes in Jesus has one assurance his spirit will be alive. He will be alive in spirit from the moment he believe. This live will continue whole over through out eternity.
