Rev 21:4, 1 Cor 13:12, Col 3:4, Rev 22:3-4
Many people expect that when they go to heaven there will be no sorrow, only happiness. Of course it will. (Rev 21:4)
Rev 21:4 And God shall wipe away all tears from their eyes; and there shall be no more death, neither sorrow, nor crying, neither shall there be any more pain: for the former things are passed away.
However, the reality is that heaven is a place where we meet God who loves us and Christ Jesus, who died for us. (1 Cor 13:12, Col 3:4, Rev 22:3-4)
1 Cor 13:12 For now we see through a glass, darkly; but then face to face: now I know in part; but then shall I know even as also I am known.
Col 3:4 When Christ, who is our life, shall appear, then shall ye also appear with him in glory.
Rev 22:3 And there shall be no more curse: but the throne of God and of the Lamb shall be in it; and his servants shall serve him: 4 And they shall see his face; and his name shall be in their foreheads.
