This is why (1) we are commanded to sing the Psalms (cf. Eph. 5:19; Col. 3:16) and (2) so many of the psalms speak of “enemies” (e.g., Ps. 3:7; 5:8; 6:7,10; 7:6; 8:2; etc.). This is also why the imprecatory psalms, the psalms calling down curses upon the enemies of God, are important for us to sing. By singing them, we call upon God to go to war against His enemies —to conquer them by converting them (cf. Ps. 83:16) or destroying them (cf. Ps. 137).
