David prayed, "Search me, God, see if there's "any offensive way” in me." When you pray that kind of prayer, God is going to show you things that have to go so that He can reclaim your heart, these things that you’ve allowed that have not only captured your heart, but have created a stronghold in your mind. A stronghold is considered a thought or behavior that is not pleasing to the Lord that you cannot seem to stop. Asking God to search your heart is inviting Him to show you areas of impurity so that He can bring you into a deeper relationship with the Holy Spirit, transforming you to become more like Jesus.
