Would a king take it well at our hands, if, when speaking to us, we should be playing with a feather? When God is speaking to us in His Word, and our hearts are taken up with thoughts about the world, is not this playing with a feather? Oh, how should this humble most of us, that we do not make God to be a God to us! We do not believe in Him, love Him, worship Him as God. Many heathens have worshiped their false gods with more seriousness and devotion than some Christians do the true God. O let us chide ourselves; did I say chide? Let us abhor ourselves for our deadness and formality in religion; how we have professed God, and yet have not worshipped Him as God.
