The Root of Worship
We are more than just servants to our Heavenly Master. We are children—sons and daughters, and He is our Father. We know that Matthew tells us that God, our Heavenly Father, would prefer to give us the greatest gifts. God does not just give a gift to clean up the storehouse of Heaven. God knows exactly how he wants to distribute gifts. He gives them according to our ability. Our job as children of God is to become intimate with Him. We are to live so close to His heart that we "know" him. We need to know Him as much more than a God of wrath, but also a God of perfect love. When we understand that, we will see that offering anything less than everything would be a compromise in our worship.
The final thing that we see from Romans 12:1 is the reward of worship. When we engage in true worship we will become holy and acceptable to God, and that is the goal and motivation behind everything that we do in worship. Now you must understand that this does not mean that we can manipulate God. It would be arrogant on our part to think that we can perform certain "worship rituals" to the point the God will give us what we want. The ritual does not please God. Even though there are "rituals" and actions that we do in worship, God still desires a heart that loves Him and is devoted to His calling and leading.
