The Bible does not describe in detail what life in eternity will be like, but it does reveal to us that being with Christ in heaven is "far better" than our present circumstance. "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" (Rev. 22:3).
Best of all, everyone (believer and non-believer) will see the Lord Jesus face to face. Our deepest yearning will be fully and completely satisfied in Him. To be with Jesus forever is the sum of all happiness.
