God has revealed what He wants all His people to do on His day:
Psa 92:1 <A Psalm or Song for the sabbath day.> It is a good thing to give thanks unto the LORD, and to sing praises unto thy name, O most High:
2 To shew forth thy lovingkindness in the morning, and thy faithfulness every night,
3 Upon an instrument of ten strings, and upon the psaltery; upon the harp with a solemn sound.
4 For thou, LORD, hast made me glad through thy work: I will triumph in the works of thy hands.
Under inspiration, the Psalmist exclaims that it is good to sing praises to God’s name using stringed instruments both in the morning and in the night on the Sabbath Day. This is one of the clearest passages that teaches the importance of corporate worship both in the morning and in the evening on the one day of the week that God specifically set aside to be uniquely His.
For NT believers, the Lord’s Day is that day. Based on the teaching of this passage, believers all over the world need to accept the truth that worshiping God corporately both in the morning and in the evening on the Lord’s Day with the use of singing accompanied by musical instruments is a good thing that God wants us to do every week.
I think it is very disturbing and concerning that churches are discontinuing corporate worship services on the Lord’s Day, especially in the evenings. We should use passages such as this one to disciple believers all over the world about what God wants His people to do on His day.
We should also strongly encourage our brethren that developing skillfulness in instrumental musical ministry is an essential aspect of giving God the glory due His name.
