God's mercies must move us to please God.
Romans 12:1 I beseech you therefore, brethren, by the mercies of God, that ye present your bodies a living sacrifice, holy, acceptable to God, [which is] your reasonable service. Romans 12:2 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.
No man must think too well of himself,
Romans 12:3 For through the grace given to me, I say, 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. Romans 12:4 For as we have many members in one body, and all members have not the same office: Romans 12:5 So we, [being] many, are one body in Christ, and every one members one of another.
but attend, every one, on that calling wherein he is placed.
Romans 12:6 Having then gifts differing according to the grace that is given to us, whether prophecy, [let us prophesy] according to the proportion of faith; Romans 12:7 Or ministry, [let us wait] on [our] ministering: or he that teacheth, on teaching: Romans 12:8 Or he that exhorteth, on exhortation: he that giveth, [let him do it] with simplicity; he that ruleth, with diligence; he that showeth mercy, with cheerfulness.
Love, and many other duties, are required of us.
Romans 12:9 [Let] love be without dissimulation. Abhor that which is evil; cleave to that which is good. Romans 12:10 [Be] kindly affectioned one to another with brotherly love; in honor preferring one another; Romans 12:11 Not slothful in business; fervent in spirit; serving the Lord; Romans 12:12 Rejoicing in hope; patient in tribulation; continuing earnest in prayer; Romans 12:13 Distributing to the necessity of saints; given to hospitality. Romans 12:14 Bless them who persecute you; bless, and curse not. Romans 12:15 Rejoice with them that rejoice, and weep with them that weep. Romans 12:16 [Be] of the same mind one towards another. Mind not high things, but condescend to men of low estate. Be not wise in your own conceits. Romans 12:17 Recompense to no man evil for evil. Provide things honest in the sight of all men. Romans 12:18 If [it is] possible, as much as lieth in you, live peaceably with all men.
Revenge is specially forbidden.
Romans 12:19 Dearly beloved, avenge not yourselves, but [rather] give place to wrath: for it is written, Vengeance [is] mine; I will repay, saith the Lord. Romans 12:20 Therefore if thy enemy hungereth, feed him; if he thirsteth, give him drink: for in so doing thou shalt heap coals of fire on his head. Romans 12:21 Be not overcome by evil, but overcome evil with good.
