John 11:25-26 Jesus told her, "I am the resurrection and the life. Those who believe in me, even though they die like everyone else, will live again. They are given eternal life for believing in me and will never perish. Do you believe this, Martha?"
Jesus is the resurrection and life. Without the resurrection, there is no life. If Jesus had not risen from the grave, no one would make it into heaven. We would all be bound for hell because our righteousness is as filthy rags. We cannot be good enough on our own for heaven. We would be spiritually dead with no hope of life.
The resurrection opened the door of heaven for all who would believe in Him and accept Him as Savior and Lord. The resurrection is God's exclamation point on the work Christ completed for us at Calvary. There Jesus took the condemnation of all sin upon himself. He overcame Satan's hold on the sinful soul. He took the worry and fear of death away from those who believe. He connected us with God and made available to us all the resources of heaven to help us live righteous lives before God.
The resurrection is God's guarantee that all who believe in what Jesus has done for them, confess their sins to Him, seek His forgiveness, and let Him into their hearts will be saved and live forever with Him.
The question is not whether or not it is so; it is whether or not you believe it is so. And, if you believe it is so, are you living like it it is? Eternal life with God awaits those who trust in Jesus for their salvation and live godly lives.
