The cloud-filled blue sky gives coolness and extraordinary comfort. The sky of the day or night remains the same, the sky in the daytime will be filled with clouds of various shapes. Clouds never leave the sky, either rain or hot, although the sky becomes dark because night comes but the cloud will remain with the sky.
For me the sky is still beautiful to tell, the day the heavens are filled with clouds while the night sky will be filled with stars that are scattered unless the sky is cloudy would not look the star. What a beautiful and perfect creation God can not match.
