We can often give into our sensory mechanism's and emotions and allow them to lead us. We jump, flinch and fight the wrong fight. God simply wants hold fast and let him fight the battle. We can only do this when we fully trust him and when we fall short, there's grace for that.
Don't let the enemy( Satan) Get you to flinch and jump off sides. He wants you to get out of position so you will miss what God has for you.
