There are several references to feasts and banquets in Scripture. One of my favorite parties, this side of heaven, is a Worship Party. I’ve hosted two kinds of worship parties: one where I and friends lead worship and one for guitar students to lead worship.
For the personal parties, we start with a potluck dinner, then end the evening with worship and prayer. I like potlucks because if doesn’t matter if 7 people show or 50 people. There’s always enough food.
Sometimes I print up some of the words to songs so quests unfamiliar with the lyrics can sing along. Every party is different. Several of us participate in leading worship. We take turns leading songs and sharing original songs too.
