Worship is the love offering of our keen sense of the worth-ship of God.
True worship springs from the same source as the missionary himself.
To worship God truly is to become a missionary, because our worship is a testimony to Him. It is presenting back to God the best He has given to us, publicly not privately. Every act of worship is a public testimony, and is at once the most personally sacred and the most public act that God demands of His faithful ones.
