Worship is a matter of the heart. We are made to worship. We cannot not worship, just like the sun cannot not shine. It was made to do that. Shining is its nature. Worshiping is our nature. We will worship someone or something. Our purpose is to focus it in the Right Direction - Jesus.
Worship is how we live. Music is just one expression of worship. Sure, it's important. It's a beautiful gift given by God before the creation of the earth, and which will last when time is ended. But it's only one part of worship.
We who meet at the Chapel sing. (Actually, we'd be disobeying some of God's commands if we didn't.) We sing with piano and organ. We sing with guitars. We sing with strings. Occasionally we sing with voices only. We sing new. We sing old. The style is less important than the heart attitude.
Before we leave this subject: one thing we know: every old song was once new, and the age of a song is not a criterion that matters to God. We invite you to join wholeheartedly.
