Over the past several years, there's been a trend toward approaching worship "vertically." We're told as worship leaders to lead people in direct, first-person worship of God; to sing songs to God rather than songs about God. But that, by itself, affirms an individualistic attitude that should be foreign to the body of Christ. For we are one body, members of one another, with a single head, who is Christ (Ephesians 4). And we should encourage one another, stimulating each other to love and good deeds (Hebrews 10).
I'm challenged to find and to write songs that aim towards this horizontal encouragement. One needs both the vertical (which is of course greater) and the horizontal to make a cross. Putting both together completes the sacrifice of worship.
