4. Worship - Proskuneo
"to make obeisance, do reverence to (from pros, towards, and kuneo, to kiss), is the most frequent word rendered worship. It is used of homage or reverence to God, to Christ, to a man, to the Dragon, to the Beast, the image of the beast, to demons, to idols“ (Four other Greek words translated worship also mentioned, then these notes:) The worship of God is nowhere defined in Scripture. A consideration of the above verbs shows that it is not confined to praise; broadly it may be regarded as the direct acknowledgement to God, of his nature, attributes, ways and claims, whether by the outgoing of the heart in praise and thanksgiving or by deeds done in such acknowledgment. In Acts 17:25 therapeuo, to serve, do service (so R.V.) is rendered 'is worshipped'."

10. “Must Worship Him” "In Spirit"
"The word spirit, here, stands opposed to rites and ceremonies, and to the pomp of external worship. It refers to the mind, the souls, the heart. They shall worship God with a sincere mind; with the simple offering of gratitude and prayer; with a desire to glorify him, and without external pomp and splendour. Spiritual worship is that where the heart is offered to God, and where we do not depend on external forms for acceptance." (Barnes Notes, John 4:23.)

11. “Must Worship Him” "In Truth"
"Not through the medium of shadows and types, not by means of sacrifices and bloody offerings, but in the manner represented or typified by all of these, Heb 9:9,24. In the true way of direct access to God through Jesus Christ." (Barnes Notes, John 4:23.)
