"What are your services like?"

Simple, friendly, and Biblical (and not really that long either :).

The worship of the church of Christ is plainly given in the New Testament. Jesus said: “God is Spirit: and those who worship Him must worship in spirit and in truth” (John 4:24). The day Christians worship is Sunday, the first day of the week (Acts 20:7; 1 Corinthians 16:2). The ways Christians worship are: singing, preaching, praying, giving, and the communion (Colossians 3:16; 1 Timothy 2:1-2; Acts 20:7; 2 Timothy 4:2; 1 Corinthians 16:1-2).
