Is any [among you] merry? let him sing psalms. — James 5:13b
This is a challenge to me: I need to learn more Psalms. Jamie Soles has been helpful to me in this area; across his albums our family has been exposed to nearly fifty Psalms or parts of Psalms.
This verse also lends support for Jordan’s law of preponderant psalmody, if you recall that God wants his people to make merry whenever they gather to stand before his throne (Deut. 14:22ff, Neh. 8:9-12).
