"And so, dear brothers and sisters, I plead with you to give your bodies to God because of all he has done for you. Let them be a living and holy sacrifice—the kind he will find acceptable. This is truly the way to worship him. Don’t copy the behavior and customs of this world, but let God transform you into a new person by changing the way you think. Then you will learn to know God’s will for you, which is good and pleasing and perfect.
"
Romans 12:1-2 NLT. Living sacrifices, what does that even mean? The concept of a living sacrifice is somewhat foolish and contrary to reasoning and nature, no one expects a sacrifice to be alive on the altar. Things die on the altar. Normally, a sacrifice, if it has been offered, should be dead on the altar.
Paul says for us Christians, we are alive on the altar both to God and to the people around us. We worship God in Spirit and at the same time, we are the very fragrance people will see and taste God. We are the righteousness of God who worship God in the Spirit and have no confidence in the flesh. We are the salt and light of our world. My encouragement; never forget you are a living sacrifice.
