Liturgy can present the letter-G word: God.
However knowing God personally is much more than a word or a ritual. It requires direct encounter followed by daily surrender to and obedience to His will.
Liturgy began as spiritual life, as the outflow of the Holy Spirit through individuals; but gradually became form and ritual rather than life. Paul of Tarsus warns us to beware of “having a form of godliness, but denying the power thereof.”
Liturgy became driven by human memory and habit more than by the inward flow of spiritual life. However, when people who don’t know liturgy begin to allow the Holy Spirit’s current to flow in them, the life flowing through them spontaneously moves them to act in ways that can look similar to liturgy — chanting, singing, bowing, quoting Scripture, etc.
Is your relationship with God dependent on liturgy? Or is it based on the living Holy Spirit working in and flowing through your heart?
