A rainbow is not a physical object that can be approached or touched but a mere reflection of light entering every single droplet to form a magnificent display. The rainbow in Noah's time was the evidence of God's promise to never again destroy life with water. The Lord used the rainbow as His signature on the Covenant between God and man; a covenant of love and hope.
We wish that every Promise of God could be visible like the rainbow. But not all are.
Could there be someone any more pitiful than Job? His livestock, enough to cover a mountain, was robbed, all his possessions were lost; his body became covered with boils; his wife turned her back on him and asked him to abandon God, his friends despised him; and the saddest blow of all, he lost his children. I would say this is also a catastrophe of epic proportions unfolding before his very eyes. Where is the rainbow in all this flooding of crisis after crisis?
But instead of sinning with his lips, Job sought and waited for God's will to be revealed to Him, and eventually he was able to bear resounding witness for God by saying:
"Jehovah gave, and Jehovah has taken away; blessed be the name of Jehovah"
~ Job 1:21
Through all these storms, Job did not see THE RAINBOW... JOB SAW THE FACE OF GOD! He may have been tempted to question Him, but he remained steadfast, and God honored and strengthened his faith. Job did not seek for a rainbow, or the rays of sun behind the rainfall, but he looked for the SON beyond the storm.
And his reward came more than what his human mind can imagine. It did not come quickly though, but it did! God's answer was sure.
"12 Now the Lord blessed the latter days of Job more than his beginning; for he had fourteen thousand sheep, six thousand camels, one thousand yoke of oxen, and one thousand female donkeys. 13 He also had seven sons and three daughters. 14 And he called the name of the first Jemimah, the name of the second Keziah, and the name of the third Keren-Happuch. 15 In all the land were found no women as beautiful as the daughters of Job; and their father gave them an inheritance among their brothers. 16 After this Job lived one hundred and forty years, and saw his children and grandchildren for four generations. 17 So Job died, old and full of days."
~ Job 42: 12 -17 NKJV
Oh that we may see God's rainbows after all our sorrows, our afflictions, our trials and tribulations. Yet, despite all these that we experience in our lifetime, there is a rainbow far above that eyes have not seen nor ears heard awaiting those faithful ones who will remain steadfast till the end.
Revelation 4: 1 -3 NLT says,
"Then as I looked, I saw a door standing open in heaven, and the same voice I had heard before spoke to me like a trumpet blast. The voice said, “Come up here, and I will show you what must happen after this.” And instantly I was in the Spirit, and I saw a throne in heaven and someone sitting on it. The one sitting on the throne was as brilliant as gemstones—like jasper and carnelian. And the glow of an emerald circled his throne like a rainbow."
