There is a point of no return DBT9 as Pharaoh reacted to the plagues his heart became less flesh and more stone.
God will hand over the rebel man to the desires of his own heart, rebellion has a finite point in time for every man.
Exodus 8 King James Version
8 Then Pharaoh called for Moses and Aaron, and said, Intreat the Lord, that he may take away the frogs from me, and from my people; and I will let the people go, that they may do sacrifice unto the Lord.
9 And Moses said unto Pharaoh, Glory over me: when shall I intreat for thee, and for thy servants, and for thy people, to destroy the frogs from thee and thy houses, that they may remain in the river only?
10 And he said, To morrow. And he said, Be it according to thy word: that thou mayest know that there is none like unto the Lord our God.
11 And the frogs shall depart from thee, and from thy houses, and from thy servants, and from thy people; they shall remain in the river only.
12 And Moses and Aaron went out from Pharaoh: and Moses cried unto the Lord because of the frogs which he had brought against Pharaoh.
13 And the Lord did according to the word of Moses; and the frogs died out of the houses, out of the villages, and out of the fields.
14 And they gathered them together upon heaps: and the land stank.
15 But when Pharaoh saw that there was respite, he hardened his heart, and hearkened not unto them; as the Lord had said.
