Paul, as he wrote this letter to the Roman church, referred to the life in Christ as to a sacrifice.
Paul said that sacrifice can only be given as we do not conform (to this world) but as we are transformed as the Holy Spirit provides those things we need to become a new creature.
Romans 12:1-21 (KJV)
1 I beseech you therefore, brethren, by the mercies of God, that ye present your bodies a living sacrifice, holy, acceptable unto God, which is your reasonable service.
2 And be not conformed to this world: but be ye transformed by the renewing of your mind, that ye may prove what is that good, and acceptable, and perfect, will of God.
3 For I say, through the grace given unto me, to every man that is among you, not to think of himself more highly than he ought to think; but to think soberly, according as God hath dealt to every man the measure of faith.
4 For as we have many members in one body, and all members have not the same office:
5 So we, being many, are one body in Christ, and every one members one of another.
6 Having then gifts differing according to the grace that is given to us, whether prophecy, let us prophesy according to the proportion of faith;
7 Or ministry, let us wait on our ministering: or he that teacheth, on teaching;
8 Or he that exhorteth, on exhortation: he that giveth, let him do it with simplicity; he that ruleth, with diligence; he that sheweth mercy, with cheerfulness.
9 Let love be without dissimulation. Abhor that which is evil; cleave to that which is good.
10 Be kindly affectioned one to another with brotherly love; in honour preferring one another;
11 Not slothful in business; fervent in spirit; serving the Lord;
12 Rejoicing in hope; patient in tribulation; continuing instant in prayer;
13 Distributing to the necessity of saints; given to hospitality.
14 Bless them which persecute you: bless, and curse not.
15 Rejoice with them that do rejoice, and weep with them that weep.
16 Be of the same mind one toward another. Mind not high things, but condescend to men of low estate. Be not wise in your own conceits.
17 Recompense to no man evil for evil. Provide things honest in the sight of all men.
18 If it be possible, as much as lieth in you, live peaceably with all men.
19 Dearly beloved, avenge not yourselves, but rather give place unto wrath: for it is written, Vengeance is mine; I will repay, saith the Lord.
20 Therefore if thine enemy hunger, feed him; if he thirst, give him drink: for in so doing thou shalt heap coals of fire on his head.
21 Be not overcome of evil, but overcome evil with good.
Romans 12:1-21 (CEV)
1 Dear friends, God is good. So I beg you to offer your bodies to him as a living sacrifice, pure and pleasing. That's the most sensible way to serve God.
2 Don't be like the people of this world, but let God change the way you think. Then you will know how to do everything that is good and pleasing to him.
3 I realize how kind God has been to me, and so I tell each of you not to think you are better than you really are. Use good sense and measure yourself by the amount of faith that God has given you.
4 A body is made up of many parts, and each of them has its own use.
5 That's how it is with us. There are many of us, but we each are part of the body of Christ, as well as part of one another.
6 God has also given each of us different gifts to use. If we can prophesy, we should do it according to the amount of faith we have.
7 If we can serve others, we should serve. If we can teach, we should teach.
8 If we can encourage others, we should encourage them. If we can give, we should be generous. If we are leaders, we should do our best. If we are good to others, we should do it cheerfully.
9 Be sincere in your love for others. Hate everything that is evil and hold tight to everything that is good.
10 Love each other as brothers and sisters and honor others more than you do yourself.
11 Never give up. Eagerly follow the Holy Spirit and serve the Lord.
12 Let your hope make you glad. Be patient in time of trouble and never stop praying.
13 Take care of God's needy people and welcome strangers into your home.
14 Ask God to bless everyone who mistreats you. Ask him to bless them and not to curse them.
15 When others are happy, be happy with them, and when they are sad, be sad.
16 Be friendly with everyone. Don't be proud and feel that you are smarter than others. Make friends with ordinary people.
17 Don't mistreat someone who has mistreated you. But try to earn the respect of others,
18 and do your best to live at peace with everyone.
19 Dear friends, don't try to get even. Let God take revenge. In the Scriptures the Lord says, "I am the one to take revenge and pay them back."
20 The Scriptures also say, "If your enemies are hungry, give them something to eat. And if they are thirsty, give them something to drink. This will be the same as piling burning coals on their heads."
21 Don't let evil defeat you, but defeat evil with good.
