Service with a Spiritual Gift Is an Act of Worship
New Testament believers are called priests, both men and women. The prerequisite for priesthood is to confess Jesus Christ as Savior, be saved, and be anointed by the Holy Spirit. Every believer has experienced those things. That gives us the privilege of serving as priests as Romans 12 said.
I urge you therefore, brethren, by the tender mercies of God, to present your bodies a living and holy sacrifice, acceptable to God, your priestly service of worship. (Rom 12:1)
The phrase priestly service of worship gives the reason to present our bodies to God. We have been granted the privilege of worship but the only way that can be activated is by the functioning of our body. A non-movable body would make a very poor priest. Priests do things and in order to do so they must move their bodies. So in this last half of Romans, Paul the Apostle said that our bodies must be offered to God as a living sacrifice unlike the dead sacrifices of the Old Testament. The next question is what are the sacrifices that we offer since we will never offer the animal sacrifices of the Old Testament? Christ has nullified the Old Testament sacrifices and instituted a new set of spiritual sacrifices. Tomorrow's devotional will start telling us what they are.
