Believers tremble and bow in fear to the devil only when they fail to identify that the Almighty God is the Mighty Warrior who has never a battle and will never lose a war. The Lord of hosts is our defender. He is the only one that can keep us safe and guide us into victory. Bowing in fear will irritate the Lord, to say the least, because He has instructed us that Thou shalt have no other gods before me.
This is the reason the Lord Jesus came to save those who because of the fear of death have kept themselves into eternal bondage. The Almighty God is the Greatest Warrior. Israelites experienced the great word of the Lord and they composed a song as we read in Exodus 15:1-11.
You have to be saved by the Lord to enjoy His great deeds. The children of Israel were always witnesses to the great deeds of the Lord because they belonged to Him they were His children. To experience the great work of the Lord, you need to save by the precious blood of Jesus Christ. This is the first great deed God does in the lives of His people the salvation of their souls.
