Worship that means just talk is called "lip service"; when you SAY that you believe something that you really don't. "Lip service" can be applied to religion, politics, any cause you SAY you follow when you don't.
To worship God in spirit and in truth, then, is to declare that God is worthy of our reverence. We do this both through our emotional core and in light of reality. We worship God based on the truth of who He is, the truth of who we are, the truth of what God does, and the truth of what is going on in our world. We do it with a heart inclined toward God and in submission to Him. We worship God when our attitudes, actions, and words declare that He is worthy of our praise.

In David’s day, “the house of Jehovah” was the tabernacle. It was David himself who made arrangements for the elaborate temple structure that was to be built by his son Solomon. Centuries later, Jesus revealed that rendering acceptable worship to Jehovah would no longer be contingent on having one grand structure that was blessed by God. (John 4:21-23) The apostle Paul indicated in Hebrews chapters 8 to 10 that a great spiritual temple came into existence at Jesus’ baptism in 29 C.E., when he presented himself to do Jehovah’s will. (Heb. 10:10) This great spiritual temple is the arrangement Jehovah has made so that we, through our faith in Jesus’ ransom sacrifice, can approach God acceptably. How do we worship there? By praying “with true hearts in the full assurance of faith”; by declaring our hope publicly without wavering; and by considering, inciting, and encouraging fellow worshippers when we assemble together at our congregation meetings and during family worship. (Heb. 10:22-25) Appreciation for the arrangement of true worship fortifies us in these critical last days.
