23 But an hour is coming, and is now here, when the true worshipers will worship the Father in Spirit and in truth.[Or in spirit and truth, also in v. 24] Yes, the Father wants such people to worship him. 24 God is spirit, and those who worship him must worship in Spirit and in truth.”
John 4:23-24
True worship involves service to God
12 He answered, “I will certainly be with you, and this will be the sign to you that I am the one who sent you: when you bring the people out of Egypt, you will all worship[Or serve] God at this mountain.”
Exodus 3:12 CSB
Therefore, brothers and sisters, in view of the mercies of God, I urge you to present your bodies as a living sacrifice, holy and pleasing to God; this is your true worship.
Romans 12:1 CSB
It is not just talk:
26 If anyone[Other mss add among you] thinks he is religious without controlling his tongue, his religion is useless and he deceives himself. 27 Pure and undefiled religion before God the Father is this: to look after orphans and widows in their distress and to keep oneself unstained from the world.
James 1:26-27 CSB
