What will we do in heaven?

Heaven will embody a life of active worship and service to God as described in Revelation 22:3, where God's servants will serve Him without fatigue or weariness. This service is described as joyful, fulfilling work, different from our earthly understanding of labor. Additionally, life in heaven will be marked by perfect holiness, where believers will be free from sin and its burdens, resulting in true happiness (Matthew 5:8). Our relationship with God and our unity with fellow believers will deepen, resembling our life in Christ now but perfected and exalted in the heavenly realm.
