In Luke 10, there's a brief exchange between Jesus and a lawyer that sets the stage for Jesus to tell the famous parable of the Good Samaritan.

The lawyer asks Jesus what he must do to inherit eternal life. Jesus seems to realize that the lawyer really knows the answer already, and - indeed he does. It's one of the pithiest, most direct instructions in the whole of the Word. Here's how the lawyer states it:

"Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy strength, and with all thy mind; and thy neighbour as thyself."

Jesus simply says to him, "Thou hast answered right: this do, and thou shalt live."

So, we know what to do: Love God. Love our neighbors. We can talk a lot about how best to do that, but the "what" is plainly stated here - and it's plainly linked to the idea of eternal life.

(参照: Deuteronomy 6:5; Mark 12:33)

1017. That the nature of the multiplying depends on the character of the affection, let the person serve as an example who accepts the basic assumption that faith alone saves somebody even when he does not perform any charitable action, that is, has no charity, and so separates faith from charity. Such a person separates faith from charity not only because he has accepted that assumption since earliest childhood, but also because he really does think that if anyone were to say that charity, or the works of charity, were the essential constituent of faith and led a devout life on those grounds he would inevitably be placing merit in works, which however is a falsity. Thus he rejects charity and considers the works of charity to be worthless, and so keeps solely to the idea of faith, which is no faith at all when devoid of its essential, which is charity. As long as he confirms himself in that assumption he in no way acts from an affection for good but from the affection inherent in the delight of being able to live without any restriction on his evil desires. And anyone among those like this who relies on many different facts to confirm that assumption does not act from an affection for truth but from glory of self, in order that he may consequently appear greater, more learned, and more eminent than everybody else, and so be promoted to the ranks of the distinguished and wealthy. Thus he acts from the delight accompanying the affection, and this delight causes things of a confirmatory nature to multiply, for as stated, the character of the affection determines that of the multiplication. In general, if a basic assumption is false, nothing but falsities can possibly result from it. In fact everything conforms to the basic assumption. Indeed, as I know from experience, which in the Lord's Divine mercy I will describe elsewhere, people who confirm themselves in such basic assumptions concerning faith alone and who have not been governed at all by charity, pay no attention to, and so to speak do not see, all that the Lord has said so many times about love and charity, as in Matthew 3:8-9; 5:7, 43-48; 6:12, 15; 7:1-20; 9:13; 12:33; 13:8, 27; 18:21- end; 19:19; 22:35-39; 24:12-13; 25:34, 40, 41, 45; Mark 4:18-20; 11:13-14, 20; 12:28-34; Luke 3:8-9; 6:27-38, 43-end; 7:47; 8:8, 14-15; 10:25-28; 12:58-59; 13:6-9; John 3:19, 21; 5:42; 13:34-35; 14:15, 21, 23; 15:1-17; 21:15-17.
