First-century Christians regularly came together on the first day of the week to worship God (Acts 20:7; 1 Cor. 14:26; 16:2; Heb. 10:24-25). True worshipers follow the teaching of Jesus taught about worship. It is “in spirit and truth.” Worship “in spirit” calls on the heart as the source of our worship of God. For example, prayers and songs must be with the spirit and understanding; it is not rote ritualism (1 Cor. 14:15). True worshipers praise God “with understanding” when they sing (Psa. 47:7; Eph. 5:19; Col. 3:16). A heart far from God that goes through the motions of worship is an abomination to Him (Matt. 15:7-9). True worshipers also worship God “in truth.” His word reveals what worship He accepts. Churches of Christ gather every Sunday to pray, sing, eat the Lord’s Supper, thankfully give as we have been prospered, and listen to the teaching of God’s word (Acts 2:42; 20:7; Eph. 5:19; 1 Cor. 14:26; 16:2). Souls who worship “in spirit” are careful to give God the “in truth” worship He accepts. New Testament Christians did that. We aim to do the same today. We hope you will, too.
