Heaven is full of joy. It resounds with the praises of Him who made so wonderful a sacrifice for the redemption of the human race. Should not the church on earth be full of praise? Should not Christians publish throughout the world the joy of serving Christ? Those who in heaven join with the angelic choir in their anthem of praise must learn on earth the song of heaven, the keynote of which is thanksgiving.—Testimonies for the Church 7:244.
Everything in heaven is noble and elevated. All seek the interest and happiness of others. No one devotes himself to looking out and caring for self. It is the chief joy of all holy beings to witness the joy and happiness of those around them.—Testimonies for the Church 2:239.
There is no jar, no discord, there. All is health, happiness, and joy.—Testimonies for the Church 2:81. RRe 34
Oh, the wonders of redeeming love! the rapture of that hour when the infinite Father, looking upon the ransomed, shall behold His image, sin's discord banished, its blight removed, and the human once more in harmony with the divine! Hvn 48
I say unto you, that likewise joy shall be in heaven over one sinner that repenteth, more than over ninety and nine just persons, which need no repentance. Luke 15:7. KJV
