God is a keeper of His word. What He say, He will do. "The Lord is not slack concerning His promise, as some men count slackness" (2 Peter 3:9).
To Noah and his sons the promise was made that never again would the earth be destroyed by water. As a token of that vow, God said, "I do set My bow in the clouds..."
In the Revelation, at the beginning of chapter 4, John relates this scene:
"After this I looked, and, behold, a door was opened in heaven: and the first voice which I heard was as it were of a trumpet talking with me; which said, Come up hither, and I will shew thee things which must be hereafter. And immediately I was in the spirit: and, behold, a throne was set in heaven, and One sat on the throne. And He that sat was to look upon like a jasper and a sardine stone: and there was a rainbow round about the throne, in sight like unto an emerald" (verses 1-3).
No matter how bad the rain gets, God will never destroy the entire world with a flood. Every time I see clouds, I should by faith look for a rainbow. If I can't see it, someone can. And even when there are no clouds in the sky and not a drop of rain is falling, I can be assured that God will keep His promise: for a rainbow surrounds His throne.
This promise stands true even during life's storms. No matter how dreary the day; no matter how heavy your sorrow; no matter how imperfect you are; no matter how much of your life is crashing in on you -- it will never get so bad as to swallow you up; for a rainbow surrounds God's throne.
"There hath no temptation taken you but such as is common to man: but God is faithful, who will not suffer you to be tempted above that ye are able; but will with the temptation also make a way to escape, that ye may be able to bear it" (1 Corinthians 10:13).
Look by faith into heaven, and see the rainbow around the Father's throne.
For He is faithful.
