You don't go alone to the place of your destiny.
Both God and the enemies go with you.
Israel under the leadership of Moses left Egypt. God led them out and also gave them strong confidence in Him when he opened up the Red Sea.
The entered a new path to great destiny with God yet the enemy followed them.
But God fought for them.
Please understand that when you experience terrifying challenges after prayer and fasting does not mean your prayers were not answered. It simply means you are now walking on the pathway of glory.
Rest in the hands of God. Trust him and let him. Judge.5:20 says that "They fought from heaven". Your new challenge is no match to heaven. The Lord who troubled the Egyptians will trouble your enemies and give you the final victory in Jesus Name.
