Isaiah 65:24 And it shall come to pass, that before they call, I will answer; and while they are yet speaking, I will hear.
This doesn’t mean to say that there were not times when folks had to wait but God usually would come through with an answer in ways that would bring a clarity and certainty to the request, in so much that the petitioner would be quite confident beyond the shadow of a doubt that God had heard them and He answered their prayers.
The reason for this, in many cases, was that in the other areas of their lives, believers back then were in the habit of acknowledging God in all their ways, and in this way He could direct their paths aright. It isn’t genuine faith which claims the promises of God on the one hand, while excluding Him from another area where we choose man’s counsel above God’s.
In the case of Isaac, when he was about to embark upon his life’s journey, with the girl of his dreams, we find His father praying, he himself praying, and the servant Eliezer praying. And lo and behold, the servant was not finished praying, before the direct answer came.
Psalms 66:19 But verily God hath heard me; he hath attended to the voice of my prayer. 20 Blessed be God, which hath not turned away my prayer, nor his mercy from me.
May The Lord add His blessing to the study of His word. God bless!
