The quote you are referring to is most likely: "Said the angel: 'If such should be ushered into the city of God, and told that all its rich beauty and glory was theirs to enjoy eternally, they would have no sense of how dearly that inheritance was purchased for them. They would never realize the matchless depths of a Saviour's love. They have not drunk of the cup, nor been baptized with the baptism. Heaven would be marred if such should dwell there. Those only who have partaken of the sufferings of the Son of God, and have come up through great tribulation, and have washed their robes and made them white in the blood of the Lamb, can enjoy the indescribable glory and unsurpassed beauty of heaven.'" — Testimonies for the Church, Volume 1, p. 155.2 (1T 155.2) This passage expresses the idea that heaven would not be truly heaven for those who have not appreciated the sacrifice of Christ, and that only those who have shared in Christ's sufferings can fully enjoy its glory. If you are looking for a different "Heaven would be enough" quote, please provide more context or clarify, and I will search again. References: White, E. G. (1868).
