Ex3:19- "But I know that the king of Egypt will not let you go unless a mighty hand forces him. NLT
When the Egyptians saw the miracles God performed through Moses, they attributed them to be the manifestation of God's finger but when God wanted to release the Israelites from the strong man that held them bound in Egypt, he had to use his strong hand. His fingers performs miracles but His hands are for deliverance.
In my little time of doing my evangelistic&teaching ministry, I have seen sons&daughters of Abraham bound and afflicted like the woman in Luke 13. I have seen those that are redeemed but not released. I have seen good christians that are better than me by my own judgement having repeated ancestral issues.
When the battle is hard and the Pharoah that has held you bound doesn't want to set you free, the last resort is to engage the mighty hand of God. Woe unto those that do not understand the faith warfare dimension. Don't be gentle with the devil, always be on the offensive and be sure that whatever you're going through, when the mighty hand of God shows-up, victory is certain.
Father, let your mighty hand of power deal with the Pharaoh troubling my life In Jesus Name.
