1 I appeal to you therefore, brothers, by the mercies of God, to present your bodies as a living sacrifice, holy and acceptable to God, which is your spiritual worship.
which is your spiritual [reasonable] worship.
The word “spiritual” is a term connoting logic (reasonable), carrying the idea of what is appropriate. There is a logic to worshipping God by presenting ourselves to Him because He has done so much for us in grace (chapters 9 to 11). It stands to reason that we serve the Lord because of all that He has done for us.
“Worship” is ministry to God in the same way priests of the Old Testament served. However, this particular verse does not refer to public worship but to worship by an individual.
It stands to reason that we dedicate ourselves to God, who has done so much for us.
Christian worship is a logical commitment. It is not worship based on unadulterated emotion or experience. This worship rests on clear reasoning. We clearly understand the logic of justification and positional truth, among other doctrines.
