I don't go to a church but my favorite part of my Messianic excursion has got to be seeing how other Christians practice their faith. For example: I will probably never stop being intrigued by the thought of a large group getting together and singing as an act of worship.
It's an act that has been recorded since the Old Testament. I do it by myself (yes, I spontaneously break into song - oddly enough it usually ends up being a Christmas song), with my family, and with the Church. I think it's great that one of the things God desires for worship (singing) is actually fun to do. Sure beats pagan rituals of sacrificing your children or cutting yourself.
Exodus 15:1
Then Moses and the Israelites sang this song to the Lord:
"I will sing to the Lord, for he is highly exalted. Both horse and driver he has hurled into the sea..."
Numbers 21:17
Then Israel sang this song:
"Spring up, O well! Sing about it,..."
Psalm 96:1
Sing to the Lord a new song; sing to the Lord, all the earth.
Ephesians 5:19-20
speaking to one another with psalms, hymns, and songs from the Spirit. Sing and make music from your heart to the Lord, 20 always giving thanks to God the Father for everything, in the name of our Lord Jesus Christ.
Colossians 3:16
Let the message of Christ dwell among you richly as you teach and admonish one another with all wisdom through psalms, hymns, and songs from the Spirit, singing to God with gratitude in your hearts.
James 5:13
Is anyone among you in trouble? Let them pray. Is anyone happy? Let them sing songs of praise.
Psalm 100:2
Worship the Lord with gladness; come before him with joyful songs.
