As believers, don't let sorrow dominate our lives, but fight for joy! We are free to explore and enjoy life in Christ, not living in fear of sin. Our enjoyment is tempered by wisdom; when we cross the line into sin, it will be judged by God. Jesus lived this, enjoying everything the Father gave Him without sin, even with the knowledge that his life would end in crucifixion. He received from the Father and joyfully gave to those around Him. Our most effective witness: spread the gospel with joy!
