Jesus says in John 4:23-24, “But the hour is coming, and now is, when true worshippers will worship the Father in spirit and in truth, for the Father is seeking such to worship Him. God is a spirit and they that worship Him must worship Him in spirit and in truth.” It doesn’t say we can worship God anyway we want, but we “must worship Him in spirit and in truth”. The word “must” makes it absolute. There is no other way we can worship God and be acceptable to Him. The word “must”, according to Webster, expresses “an obligation, a requirement, a necessity, a certainty, and something that must be done”. When “must” is used it means that it is not optional. Here the word “must” is expressing that in spirit and in truth is the only way to acceptably worship God. God seeks true worshippers, and He identifies them as those who “worship Him in spirit and in truth”. Worshipping God in spirit and in truth is a serious matter which must not be taken lightly. If we have any regard for our own souls, we will want to make sure we are worshipping God in spirit and in truth.
