Worship is kindled within us only when the Spirit of God touches our human spirit. We can use all the right techniques and methods, we can have the best possible liturgy, but we have not worshipped the Lord until Spirit touches spirit. As worship leaders, we are left with two choices in the way in which we lead — initiation or response. Initiation is often how we lead, trying to force people into worship and making things happen in our own strength. The far better way is to lead by responding to what the Spirit is doing. There lies the blessing.
William Barclay: The true, the genuine worship is when man, through his spirit, attains to friendship and intimacy with God. True and genuine worship is not to come to a certain place; it is not to go through a certain ritual or liturgy; it is not even to bring certain gifts. True worship is when the spirit, the immortal and invisible part of man, speaks to and meets with God, who is immortal and invisible.
Louie Giglio: Worship is our response, both personal and corporate, to God for who He is, and what He has done; expressed in and by the things we say and the way we live.
