Behold, he cometh with clouds; Revelation 1:7
In the Bible clouds are always associated with God. Clouds are the sorrows, sufferings, or providential circumstances, within or without our personal lives, which actually seem to contradict the sovereignty of God. Yet it is through these very clouds that the Spirit of God is teaching us how to walk by faith. If there were never any clouds in our lives, we would have no faith. “The clouds are the dust of His feet” (Nahum 1:3). They are a sign that God is there. What a revelation it is to know that sorrow, bereavement, and suffering are actually the clouds that come along with God! God cannot come near us without clouds— He does not come in clear-shining brightness.
It is not true to say that God wants to teach us something in our trials. Through every cloud He brings our way, He wants us to unlearn something. His purpose in using the cloud is to simplify our beliefs until our relationship with Him is exactly like that of a child— a relationship simply between God and our own souls, and where other people are but shadows. Until other people become shadows to us, clouds and darkness will be ours every once in a while. Is our relationship with God becoming more simple than it has ever been?
