I haven't been there but I believe it will answer a lot of things for everyone. It will confirm if there is afterlife. Before I go on let me make it clear that I believe there is heaven and that everything the Bible says about it is true.Every people in the world believe in some kind of heaven but could we all be right ? That will be confirmed in heaven.
In my life I have been to most Christian churches. We believe in one God. The Bible revealed there is Father, Son, and Holy Spirit. Some call this Trinity and some don't. The answer will be confirmed in heaven.
Is heaven a place for devout Catholics only ? Baptists ? Pentecostals ?Muslims ? Buddhists ? Mormons ? The answer for everyone will be confirmed in heaven.
Some believe there is no heaven, well time will confirm that.
Years ago I said to one of my pastors " I am homesick for heaven." He then asked me " Have you been there ?" I guess I can not be homesick if I was never been there. But Jesus who is my Lord and Savior, said In His Father's house, are many dwelling places. That He goes to prepare a place for us that where He is there we will be also. He said He is coming back to take us into Himself. That place must be heaven, and since Jesus said it, it is good enough for me.
I understand He also takes reservation for it. That the time to make reservation for it is while we are still alive on earth. That we have to make our own reservation, no one can decide for us. How much is the cost ? It is already paid for by the death , blood, and resurrection of Jesus Christ.
To assure reservation, repent of our sins and accept Jesus Christ as Lord and Savior. Our names will be written in the Lambs Book of Life.
