No, our journey from earth to heaven won't be like modern space travel, taking perhaps millions of years for us to arrive! Don't let this concern you; when we die we won't be bound any longer by the physical limitations we experience now.
Instead, the Bible tells us that if we know Christ, we will be in God's presence immediately after we die. How is this possible? When we die, we enter into a whole new level of existence -- an existence governed by spiritual rules. After recalling all the trials and problems we experience in this life, Paul declared, "We are confident, I say, and would prefer to be away from the body and at home with the Lord" (2 Corinthians 5:8).
Never forget: You and I were not meant for this world alone. We were meant to live forever -- and we will, because death is not the end. Death instead is like a doorway, ushering us into eternity either with God in heaven, or without God and without hope in that place of absolute despair the Bible calls hell. Not one word in the Bible about heaven should make you not want to go there -- and not one word about hell in the Bible should make you want to go there.
Is heaven your hope? Do you know for sure that if you were to die tonight, you would be safely in God's presence forever? You can be sure, by trusting Christ and what He did for you by His death and resurrection. Put your faith and confidence in Him today.
