Knowledge about God.
Though KNOWLEDGE about God may be useful and is widely used in Sunday-go-meetings, KNOWLEDGE alone is an hindrance to KNOWING God personally. God's ways are beyond comprehension by man's natural KNOWER. To acquire KNOWLEDGE of God to where your KNOWER KNOWS God, we need to abide in the heart of God. To abide in the heart of God is to abide in the LOVE of God because God is LOVE. To live in His LOVE daily and lovingly love people, is truly the pure work of God. It is in the LOVE of God where the POWER of God resides and from there it is genuinely manifested.
KNOWLEDGE of God without application of God's LOVE is "another" gospel!
