2 Chron 25:2
“He (King Amaziah) did right in the sight of the Lord, yet not with a whole heart.”
We can do the right things, but have hearts that aren't totally committed to God. As worshipers, our goal is to worship God "in spirit and in truth" (John 4:24). Let it never be said of us that we "did right" in His sight, "yet not with a whole heart"!
Your heart matters most to God. In a world that says "fake it till you make it", this is an area where we, as worshipers, need to constantly be evaluating. God sees the real you, your real motivation, and the real desires of your heart.
Are there areas of your life that you are keeping from Him?
