Beloved, now are we the sons of God, and it doth not yet appear what we shall be: but we know that, when he shall appear, we shall be like him; for we shall see him as he is. 1 John 3:2.
Would you like to live your life over again? Most people say, "I surely would. There are a lot of things I'd do differently." No. Would you like to live life over again just the way you have lived it, without changing any part of it? The more one has seen of what life has to offer in this world, the quicker comes the response, "No, thanks."
Since this is true, then one of the greatest hopes that we have here is for heaven. To accept the salvation that God has provided, and to help others accept it, is our biggest purpose for being here. Aren't you thankful today that we believe in heaven?
There are many people who do not believe that heaven is a real place. But the doctrine of heaven, as a real place, is a Bible doctrine in which Seventh-day Adventists believe strongly. If heaven seems unreal to you, perhaps it is because Jesus seems unreal. A skeptic once said to a little street urchin who believed in heaven, "But what if you get to heaven, and Jesus isn't there?" And the boy replied, "Where Jesus is, that is heaven." If Jesus is real, then heaven is real.
Is Jesus real? Most people believe that He was real before His resurrection. Some have trouble believing He is real afterward. But the Bible teaches that Jesus is real post-resurrection. Luke 24:39, the disciples thought they were seeing a ghost, but Jesus said, "Behold my hands and my feet, that it is I myself: handle me, and see; for a spirit hath not flesh and bones, as ye see me have." Thomas was the doubter, but Jesus told him in John 20:27, "Reach hither your hand. Touch me. Handle me." And Thomas exclaimed, "My Lord and my God." Jesus was just as real after He was resurrected as He was before.
Add to that 1 John 3:2, "But we know that, when he shall appear, we shall be like him; for we shall see him as he is." We are going to be like Jesus when He comes again. And since Jesus is real, when we see Him face to face we will be real. Heaven won't be some vague, mystical place; it will be real.
