The word of God is the dew. Rain and dew are different. It is not sufficient for the vegetation in the field to have rain only. Therefore, in the latter part of the night , there is the descending dew (Deut. 32:2). The dew is more effective than the rain because the rainwater mostly goes to the roots, but the dew mostly descends on the leaves and branches. Everything created by God has its spiritual significance. We see that the word of God is life, the seed of life, and the rain which waters the seed; even more, it is the dew which moistens the plants.
Praise the Lord!
