Eternity
Now all of us saved sinners who have taken the free gift of eternal life, and all the Old Testament saints, and all the Tribulation saints will forever be with God. It will be perfect once again, the way things were before the fall way back in the garden. Never again will there be sin or death or sorrow or pain, only eternal happiness in which God is the center. Things will be the way they should be. Everything will work out right in the end, this life may be tough at times but the things that God has prepared for us will more than make up for it. All you have to do is accept it.
