1 Samuel 17:45.."You come to me with sword, with a spear, and with javelin, But I come to you in the name of the Lord of hosts, the God of the armies of Israel whom you have defied..." Whatever the enemy is throwing at you just like the javelin, sword and spear declare this scripture over your situation. The battle is the Lords and He will fight for you just like he did with David.
David ran towards Goliath. David knew who he was in Christ and how big his God is. Run!! Run at that giant in front of you and declare, "I come in the name of the LORD!!"
( If you are not familiar with the story of David and Goliath, read 1 Samuel 17:1-50)
