Revelations 2:7 " He that hath an ear, let him hear what the Spirit saith unto the churches; To him that overcometh will I give to eat out of the tree of life, which is in the midst of the paradise of God.
Revelation 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"
I think we can all agree that this life is not the easiest. There's lots of terrible things going on in the world, and perhaps even in our personal life. While we are on this Earth there will be times of sadness, pain , sorrow, etc; (Even Jesus wept). But we have to always look at the bigger picture; there is something to look forward to ! Our father is awaiting us in Heaven !!!!And His Word says he will wipe every tear and we will never experience sadness. The little time of suffering on this Earth will never compare to the ETERNAL happiness in Heaven.
Stay strong and have faith.
