The Old Testament is full of stories about war and fighting and how God would help His people defeat their enemies. Deuteronomy 20:4 (http://bit.ly/2pT3CqK) says “For the Lord your God is the one who goes with you to fight for you against your enemies to give you victory.”
I believe this applies today as much as it did then. We are fighting battles of a different kind: bullies, peer pressure, discrimination, racismthe list goes on. God is with us today like He was with His people then. Let God go with you and fight with you. Enjoy the victory with Him. He wants to see you win!
