Gerhard and Walther

For since the Name of God is thereby glorified if we confess our sin, so also it has to follow that through the covering up and concealment of sin, God’s Name is desecrated. God the Lord will visit and punish such concealment (Ps. 32:3-4; Pro. 28:13).—Johann Gerhard, Schola Pietatis III:277.   

False Christians also want to hold Christ and serve Him, but only as long as they can do so without sacrificing time, money, rest, honor, or any other favorite thing. The true Christian is completely different. He prefers in every case the spiritual to the bodily, the eternal to the temporal, and the heavenly to the earthly.—C. F. W. Walther, God Grant It!, p. 585 [Reflecting on the crow in Mark 8 sticking with Jesus long past the time their food ran out!]
