The singing of hymns is the same practice that the Disciples and the Lord Jesus carried out on his final night on earth. These, by the way, are the only songs practiced in this ministry. They are hymns, spiritual songs, and whatever promotes the worship of the Lord without seeming worldly (though it may be contemporary in nature with discernment) (Mt 26:30; Eph 5:19; Col 3:16;Lev 10:10-11).
