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.
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.

Thought for the Day
So it will be in the great final conflict of the controversy between righteousness and sin. While new life and light and power are descending from on high upon the disciples of Christ, a new life is springing up from beneath, and energizing the agencies of Satan. Intensity is taking possession of every earthly element. With a subtlety gained through centuries of conflict, the prince of evil works under a disguise. He appears clothed as an angel of light, and multitudes are "giving heed to seducing spirits, and doctrines of devils." 1 Tim. 4:1. Desire of Ages, p. 257
