"The hour comes, and now is, when the true worshipers shall worship the Father in spirit and in truth; for the Father seeks such to worship Him. God is a Spirit; and they that worship Him must worship Him in Spirit and in truth." (John 4:23-24)
Mark, that spiritual worship is not a privilege merely, but a necessity. Jesus did not say that they that worship God may worship Him in Spirit, but that they must do so.
There is no worship of God but spiritual worship. All professed worship of God, that is not in spirit, is but idolatry, and the taking of His name in vain.
How can we worship Him in spirit? By taking His Spirit, which He freely gives to all. Men cannot give it to us, they cannot compel us to have it; but God gives it as freely as the air, and we may have it as abundantly.--Present Truth, December 28, 1893--Timeline: III-5 (The Samaritan Woman)--John 4:23-24.
