(((Yes" I believe in the resurrection))) ==================================But tell me this?since we preach that Christ rose from the dead, why are some of you saying there will be no resurrection of the dead? For if there is no resurrection of the dead, then Christ has not been raised either. And if Christ has not been raised, then all our preaching is useless, and your faith is useless. And we apostles would all be lying about God?for we have said that God raised Christ from the grave. But that can?t be true if there is no resurrection of the dead. And if there is no resurrection of the dead, then Christ has not been raised. And if Christ has not been raised, then your faith is useless and you are still guilty of your sins. In that case, all who have died believing in Christ are lost! And if our hope in Christ is only for this life, we are more to be pitied than anyone in the world. But in fact, Christ has been raised from the dead. He is the first of a great harvest of all who have died. (1 Corinthians 15:12-20 NLT)
Yes. There are written documents Besides the Bible. 39 ancient sources Such as Pliny, Josephus, and Talmud. More than 100 prophecies from the Old Testament were fulfilled in the New Testament by Jesus. Jesus appeared to Mary Magdalene , Joanna, Mary (mother of James) , & Salome. Paul wrote that over 500 People saw Jesus after He had risen. Baptism celebrates the resurrection. The Lords Supper is a memorial to the Suffering death of Jesus. It is joy because it represents Eternal life. Belief in the living Christ is our hope To be resurrected to a new spiritual Body after we die.
Mark 5:35 "While he was still talking to her, messengers arrived from Jairus' home with the news that it was too late--his daughter was dead and there was no point in Jesus coming now. But Jesus ignored their comments and said to Jairus, "Don't be afraid Just trust me." Then Jesus halted the crowd and wouldn't let anyone go with him to Jairus home except Peter and James and John. When they arrived, Jesus saw that all was in great confusion, with unrestrained weeping and wailing. He went inside and spoke to the people. Why all this weeping and commotion?" he asked. "The child isn't dead; she is only asleep!" They Laughed at him in bitter derision, but he told them all to leave, and taking the little girl's father and mother and his three disciples, he went into the room where she was lying. Taking her by the hand he said to her, "Get up, little girl!" And she jumped up and walked around! Her parents just couldn't get over it. Jesus instructed them very earnestly not to tell what had happened, and told them to give her something to eat." (Living Bible)
The resurrection is a wonderful promise that gives us hope for the future. While Jesus was here on Earth, he resurrected people. (John 11: 43,44; Luke 8:40-56). Jehovah God resurrected Jesus three days after he was killed, as mentioned in Matthew 28:5-7. These resurrections were just a preview of things to come once the Earth is transformed into paradise. The Bible states, "Do not marvel at this, because the hour is coming in which all those in the memorial tombs will hear his voice and come out" (John 5:28, 29). Acts 24:15 mentions, "And I have hope toward God, which hope these men themselves also entertain, that there is going to be a resurrection of both the righteous and the unrighteous."
