The birth of Jesus is the fulfilment of God’s promise. Through Jesus, we can have eternal life and be united with God again. Therefore, it is a joyous day when Jesus is born. And the rainbow is the sign of the covenant between God and us.
The Bible contains all His promises. Whenever we are anxious or fearful, reading His Word gives us hope and comfort. He promised us – His children – that He will never leave us nor forsake us. He promised to protect and guide us (His children). Knowing all these, we can face our future with courage. Other than that, a rainbow is painted as the background. That is because the rainbow symbolizes that God is faithful and that He will not break His promises. The colours of the rainbow remind me of His beauty.
