Missions is not the ultimate goal of the church. Worship is. Missions exists because worship doesn't.
Don't ever think that the sin of your past means there is no hope for your future.
God wills to be displayed and known and loved and cherished and worshiped.
The immensity of His worth is reflected in the intensity of your worship.
The highest mental health is not liking myself but being joyfully interested in everything but myself.
Why Christians do what they do is just as important as what they do. Bad motives ruin good acts.
