There will be an ongoing battle for your heart. Goliath is lurking out there, and he wants to bring fear and distrust into your heart. If he does, he will ruin you for the battlefield. He’ll either distract you, lead you to stop listening, tolerate rebellion, and even fool yurself into presuming upon God.
No matter what Goliath does, his end game is to disqualify you from being a Disciple of Jesus Christ. He wants to render you worthless and ineffective.
