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. Do not be conformed to this world, but be transformed by the renewal of your mind, that by testing you may discern what is the will of God, what is good and acceptable and perfect.
For by the grace given to me I say to everyone among you not to think of himself more highly than he ought to think, but to think with sober judgment, each according to the measure of faith that God has assigned. For as in one body we have many members, and the members do not all have the same function, so we, though many, are one body in Christ, and individually members one of another. Having gifts that differ according to the grace given to us, let us use them: if prophecy, in proportion to our faith; if service, in our serving; the one who teaches, in his teaching; the one who exhorts, in his exhortation; the one who contributes, in generosity; the one who leads, with zeal; the one who does acts of mercy, with cheerfulness. Romans 12:1-8 (ESV)
It has been said that the problem with living sacrifices is that they are always wriggling themselves off of the altar. We do not live the Christian life perfectly. Thankfully in Christ, because we are baptized, and made children of God by faith, we can start each day knowing that He is renewing our minds and giving us hearts of flesh (Ezekiel 36:26) in exchange for our hearts of stone. We can trust that he forgives our sins and He gives us the strength to face a new day every day. God works this transformation in us through the Holy Spirit.
We walk a balancing act between being sinner and saint. As Paul said in Romans 8, we do the things we know we shouldn’t do, and we don’t do the things we should do. Even so, God has created each of us as an individual with a set of strengths and a set of weaknesses. Everyone has been given a vocation- a reason for being and a reason for doing- which should complement the vocations of others. A farmer grows grain for the baker to bake bread. Drivers transport raw materials so that factory workers can fabricate and assemble machines and cars and other things. Police and firefighters keep order and respond to emergencies. We have vocations in both the earthly kingdom and God’s kingdom. Sometimes they intersect, but we are made to embrace and pursue our vocations to the glory of God.
Paul has a complementary view of how we are to work together at being the Body of Christ. Some of us are positively not suited for doing certain things. Not everyone is in the position to volunteer to go do missions in Africa for a year, or to do plumbing and carpentry work, or to bake cookies. Some people have the gift of hospitality, or the ability to go abroad do missions work, but others may be more able to give financially, or teach, or encourage. Everyone has equally valid – though necessarily different and varied- vocations that we have been gifted with to serve God.
We have every reason as God’s people to appreciate and thank God for the gifts we have been given. We are also called to appreciate and thank God for the gifts God has given others, especially the gifts they share that with us we do not possess. We serve others out of a joyful response to God’s goodness, no matter what our gifts may be.
