The Empowered People of God: Wholehearted

In King Amaziah, we see a man who "did what was right in the eyes of the Lord, yet not with a whole heart" (2 Chronicles 25:2). Many in the church today are doing the right things, but their hearts are not fully given to Christ. Is there some area of your life and heart that you have fully surrendered to Jesus? If so, how do we obtain this wholeheartedness that God talks about?
