As believers, we are to worship God, to love Him with all our heart, soul, mind, and strength. We have the kingdom of God within us spiritually and are to act on this reality by separating ourselves from ways of the world. The ways of the world come from Satan, the god of this world, and have nothing in common with the kingdom of God.
What people worship is determined by their lifestyle, not something that they might do for an hour every week. The things people say and the things they do are an extension of what they value. People worship what they value by the way they live.
Therefore I urge you, brethren, by the mercies of God, to present your bodies a living and holy sacrifice, acceptable to God, which is your spiritual service of worship. And do not be conformed to this world, but be transformed by the renewing of your mind, so that you may prove what the will of God is, that which is good and acceptable and perfect. Romans 12:1-2
The decisions people will be required to make in the last days will reveal what it is that they value and worship.
