Luke 21:28 And when these things begin to come to pass, then look up, and lift up your heads; because your redemption draws nigh.
God has not left this planet to the unbridled control of evil men and evil spirits. He often permits things to come to a tipping point, or an emergency, so that when He does intervene, His interventions would be understood by all. In the days of pharaoh, God could have brought the last plague first, and the king would have let all the people go much earlier. But the Great shaper of all events allowed it to come to a crisis, so that in the fulness of time His good purposes would be fulfilled.
That this was the case can be observed by how all of the back and forth between God and pharaoh ends, with the promises, and predictions of God unfolding exactly as God had specified earlier…. Genesis 15: 13 And he said unto Abram, Know for a surety that thy seed shall be a stranger in a land that is not theirs, and shall serve them; and they shall afflict them four hundred years; 14 And also that nation, whom they shall serve, will I judge: and afterward shall they come out with great substance.
Exodus 12: 51 And it came to pass the selfsame day, that the Lord did bring the children of Israel out of the land of Egypt by their armies…. In the meantime, between the prophetic prediction and its fulfillment it might have seemed to the Hebrews that God did know what He was doing. It may have seemed as if pharaoh and his minions were running riot with no restraint from God, and at times it may have appeared that their doom was sealed.
Matthew 24: 32 Now learn a parable of the fig tree; When his branch is yet tender and puts forth leaves, you know that summer is nigh. 33 So likewise you, when you shall see all these things, know that it is near, even at the doors.
May God add His blessing to the study of His word. “Good night” and God bless!
