When we shine as lights and tell others that the kingdom of God has come, the darkness is pushed back. The work is difficult and requires courage that only God can give, but Christians always experience joy when they faithfully testify for Jesus. David did not slay Goliath by sitting back with the bread and cheese. The joy of victory comes where the battle is fought. The front lines are all around us. Those who engage in ministry have the joy of seeing Jesus work in the lives of individuals and communities.
