The battle is rough. The world is fighting against God and seeking destroy all those who believe. That's you and me. But, when we get weary we seek the Lord. We seek the Lord in his Word. The Bible tells us the truth when we need it most, wether we want it or not. When the Word tells us to love our enemies and pray for those who persecute us when we may want to destroy our enemies and curse them.
That's a hard pill to swallow sometimes. Maybe it's because God wants us to trust him with our battles. The great men and women of faith knew that the Lord was the one who fought their battles. We must be great men and women of faith and allow God to fight our battles as we seek him and serve others.
