" Music in the church ought to be much more than an emotional stimulant. In fact, this means music and preaching should have the same aim. Both properly pertain to the proclamation of God's Word. Preaching is properly seen as an aspect of or worship. And conversely, music is properly seen as an aspect of the ministry of the Word, just like preaching. Therefore the songwriter ought to be skilled in Scripture and as concerned for theological precision as the preacher. Even more so, because the songs he writes are likely to be sung again and again (unlike a sermon that is preached only once). "
