On one occasion, when Jesus talked with the Samaritan woman about the right place of worship, Jesus tells her:
23 But the hour cometh, and now is, when the true worshippers shall worship the Father in spirit and in truth: for the Father seeketh such to worship him.
24 God is a Spirit: and they that worship him must worship him in spirit and in truth.
A true worshiper has the need to worship and give praise to God, it is a growing desire that a true worshiper must have, since was created for that. As Jesus says: “must worship”.
