True worship should create God-intoxicated people.
Everyone worships. Some people worship money, possessions, popularity, prosperity, or other people. They may not sing worship songs to their bank account, but by the way they live they worship (i.e. give value to) their money.
Worship is not just singing songs in church; worship is a lifestyle that places value on its object. True worship of God means that the one worshiping is placing value on God and putting him at the center of life.
That’s what Jesus was getting at when he said, “Yet a time is coming and has now come when the true worshipers will worship the Father in spirit and truth, for they are the kind of worshipers the Father seeks. God is spirit, and his worshipers must worship in spirit and in truth.” (John 4:23-24)
Notice Jesus didn’t say anything about singing “worship songs.” To worship in spirit and in truth means that everything in your life is centered around God and guided by him — that your choices reflect him, that your actions are directed by him, and that you words are filtered through him.
In short, true worship is such that the one worshipping should be so enveloped and surrounded in the presence (the spirit) of God.
