God is growing His nature and His character in those who believe. We call this the Fruit of the Spirit.
The faithfulness that God demonstrated by keeping His promise to send His Messiah is the same faithfulness that God wants to grow in those who belong to HIm.
In a world bordering on complete chaos, believers can live in perfect peace, and demonstrate the faithfulness of God as a testimony to those around us that Jesus Christ is in fact risen from the dead.
