Purpose in your heart to serve the Lord with all your heart. Heart service is what God is after. You will only receive a head blessing if your heart is not involved. When you operate from your spirit then spiritual blessings will flow. A head belief results in a head answer. A heart belief results in a heart answer. Belief that is heart generated results in your whole being, being involved in an activity. Soul winning is a heart decision. It cannot be achieved through head knowledge. Many try to win souls through argument but it only results in head conversions. A true conversion is a heart conversion. Therefore work with your heart and decide with your head.
