God continues to increase the price to be paid for disobedience to His commands. Yet, God has a much larger plan for His people so He increases the resistance against Him by hardening Pharaoh’s heart even further than he had hardened it himself. God will deliver His people entirely out of the land. He is not satisfied with a halfway deliverance.
When we are in need, we prefer to think of a deliverance that works like the cavalry coming at the last minute while giving complete and immediate relief. God does not always work this way. Even deliverance may involve struggles and battles
