Your heart is weary of the battles that seem to take forever to fight. The battles that seem to overcome you. The battles that cause you to feel like you want to give up.
You do the only thing you know to do. You reach for His word. You open up the only weapon you have and begin to read...and pray. As you read you realize you do not fight alone. You feel His strength and His power flow through you.
It's then you understand that the battle you are fighting is one that must be fought often. It must be fought often, not because you are weak, but because God wants to make you stronger. He wants to take you deeper. Deeper into the battle, deeper into the heart, so that you can come face to face with that which keeps you in bondage. He takes you deeper in order to see your sin, your weaknesses, idols and those things that you hold on to. He takes you deeper for greater healing, and a greater victory.
So when you find yourself fighting a battle that you thought had been fought do not be discouraged. God is taking you deeper into the battle in order to grow you. So fight the good fight, keep a hold of your faith in Christ Jesus and know that He fights for you.
