With the establishment of the Christian congregation, music continued to be a prominent feature of true worship. On the most important night in human history, Jesus included the singing of songs after the institution of the Lord’s Evening Meal. First-century Christians set a pattern of praising God together in song. Even though they often met in private homes, the modest surroundings for worship did not diminish their zeal for singing to Jehovah. Under inspiration, the apostle Paul directed his Christian brothers: “Keep on teaching and encouraging one another with psalms, praises to God, spiritual songs sung with gratitude, singing in your hearts to Jehovah.” (Col. 3:16) The songs in our songbook are truly “spiritual songs [to be] sung with gratitude.” They are a part of the spiritual food provided by “the faithful and discreet slave.”​—Matt. 24:45. w17.11 4 ¶7-8
