Heaven

While Paul was on the Damascus Road on his way to persecute Christians, He saw heaven open up but whether this was heaven itself or just the first heaven where he saw the light, we cannot be sure.  Acts 9:3-4 described what Paul saw, “As he neared Damascus on his journey, suddenly a light from heaven flashed around him. He fell to the ground and heard a voice say to him, “Saul, Saul, why do you persecute me?”  We do not know for sure, according to the scriptures, whether this was the third heaven, where the throne of God was or not, but can assume it was not for Paul only heard a voice from heaven and he saw only a light from heaven.  Nonetheless, heaven is for real and it exists today in every sense of the word.
You may have read or heard about many who have died and seen heaven for themselves.  They describe such a realm that is beyond description.  Some who died and came back to life have said they have seen their lost loved ones in heaven, their family, friends, and some even their pets.  This is difficult to prove, yet the sheer number of those who have seen heaven and came back from death is hard to refute; only they themselves know this for certain.  But the Bible does describe some of what heaven is like in the scriptures.  It is, from the human standpoint, indescribable (I Cor. 2:9).
One young man asked his friend, why don't you go partying  like most of us, and the friend said, I believe in God , in heaven and hell. The young man answered,  how are you  so sure about heaven and hell, no one has seen it. The friend answered, true, I haven't seen it , I only believe what the word of God say. The friend said, I don't believe none of it, that's why I live however I want. You sure are wasting your youth not doing what you want. The friend said, Look, if its true or not what the word of God says, I will not take my chances, because what IF it's all true. Living for God may not be the easiest thing to do, but when we consider heaven our eternal home, it is all worth it!

Nothing impure will ever enter it, nor will anyone who does what is shameful or deceitful, but only those whose names are written in the Lamb’s book of life. Revelation 21:27
