Romans in a nutshell:
On the one hand,
Therefore I urge you, brothers, by the mercies of God, to present your bodies a living sacrifice, holy, acceptable to God, which is your spiritual service. Don't be conformed to this world, but be transformed by the renewing of your mind, so that you may prove what is the good and acceptable and perfect will of God. For I say, through the grace that was given me, to every man who is among you, not to think of himself more highly than he ought to think; but to think reasonably, as God has apportioned to each person a measure of faith. For even as we have many members in one body, and all the members don't have the same function, so we, who are many, are one body in Christ, and individually members one of another. Having gifts differing according to the grace that was given to us, if prophecy, let us prophesy according to the proportion of our faith; or service, let us give ourselves to service; or he who teaches, to his teaching; or he who exhorts, to his exhorting: he who gives, let him do it with liberality; he who rules, with diligence; he who shows mercy, with cheerfulness.
Let love be without hypocrisy. Abhor that which is evil. Cling to that which is good. In love of the brothers be tenderly affectionate one to another; in honor preferring one another; not lagging in diligence; fervent in spirit; serving the Lord; rejoicing in hope; enduring in troubles; continuing steadfastly in prayer; contributing to the needs of the saints; given to hospitality. Bless those who persecute you; bless, and don't curse. Rejoice with those who rejoice. Weep with those who weep. Be of the same mind one toward another. Don't set your mind on high things, but associate with the humble. Don't be wise in your own conceits. Repay no one evil for evil. Respect what is honorable in the sight of all men. If it is possible, as much as it is up to you, be at peace with all men. (12:1-18)
yet on the other
For I delight in God's law after the inward man, but I see a different law in my members, warring against the law of my mind, and bringing me into captivity under the law of sin which is in my members. What a wretched man I am! Who will deliver me out of the body of this death?(7:22-24)
…it is not of him who wills, nor of him who runs, but of God who has mercy.(9:17)
…God commends his own love toward us, in that while we were yet sinners, Christ died for us.(5:8)
Now it was not written that [righteousness] was accounted to [Abraham] for his sake alone, but for our sake also, to whom it will be accounted, who believe in him who raised Jesus, our Lord, from the dead, who was delivered up for our trespasses, and was raised for our justification.
Being therefore justified by faith, we have peace with God through our Lord Jesus Christ; through whom we also have our access by faith into this grace in which we stand. We rejoice in hope of the glory of God.(4:23-5:2)
