No, I cannot prove that there is a heaven. Since we cannot see heaven, it is something that must be accepted by faith. Most people believe that there is some kind of a heaven to go to after death. If you do not believe in heaven, do you ever wish that there was such a place? Do you ever wish that, after you die, you could spend eternity in a place where you would be happy, truly loved, and completely satisfied? Do you ever wish that you could see loved ones again who have passed away, and have the assurance that they are in a better place? Or, do you believe that it all ends at death; that you will never see your loved ones again and that this life, full of pain, suffering and sickness, is all that there is? If you believe that, then you cannot possibly believe that there is a God. How could God create human beings to live on this earth, many with a life of sorrow, suffering and hopelessness and then have it all end in a grave somewhere? Because it makes no logical sense to believe that there is no God, then it also makes no sense to believe that there is no heaven.
The Bible says, “But I would not have you to be ignorant, brethren, concerning them which are asleep, that ye sorrow not, even as others which have no hope. For if we believe that Jesus died and rose again, even so them also which sleep in Jesus will God bring with him.” (1 Thessalonians 4:13-14) Wouldn’t it be a terrible thing to sorrow with no hope of ever seeing our loved ones again after death? Many people do not have any hope at all. The Bible tells us that hope comes through the Lord Jesus Christ. Jesus believed in heaven and taught about it. “Let not your heart be troubled: ye believe in God, believe also in me. In my Father's house are many mansions: if it were not so, I would have told you. I go to prepare a place for you. And if I go and prepare a place for you, I will come again, and receive you unto myself; that where I am, there ye may be also.” (John 14:1-3)
Heaven is a matter of faith and also, some logic. Faith tells me to believe Jesus when he says, “For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.” (John 3:16) Logic tells me that there is a God and that God is good. A good God cannot possibly leave millions of people to live their lives in an aimless and hopeless existence without giving them some way to spend eternity in real peace and happiness
