Psalm 119:9-16

How can young people keep their way pure?

   By guarding it according to your word.

With my whole heart I seek you;

   do not let me stray from your commandments.

I treasure your word in my heart,

   so that I may not sin against you.

Blessed are you, O Lord;

   teach me your statutes.

With my lips I declare

   all the ordinances of your mouth.

I delight in the way of your decrees

   as much as in all riches.

I will meditate on your precepts,

   and fix my eyes on your ways.

I will delight in your statutes;

   I will not forget your word.

Matthew 5:27-32

‘You have heard that it was said, “You shall not commit adultery.” But I say to you that everyone who looks at a woman with lust has already committed adultery with her in his heart. If your right eye causes you to sin, tear it out and throw it away; it is better for you to lose one of your members than for your whole body to be thrown into hell. And if your right hand causes you to sin, cut it off and throw it away; it is better for you to lose one of your members than for your whole body to go into hell.

 ‘It was also said, “Whoever divorces his wife, let him give her a certificate of divorce.” But I say to you that anyone who divorces his wife, except on the ground of unchastity, causes her to commit adultery; and whoever marries a divorced woman commits adultery.

Arcana Coelestia 8911

From what has been thus far said it can be seen how the case is with man and his life, namely, that man is such as his will is, and that he remains such after death, because death is not the end of life, but its continuation. As therefore man is such as his will is, because, as before said, the will is the man himself, therefore "to be judged according to his deeds" signifies to be judged according to his will, for will and deed are not at variance, the deed being in the will and the will in the deed, provided external bonds do not hinder, such as fears of the law, of the loss of honor, of gain, of reputation, and of life. This is circumstanced like endeavor and motion. Motion is nothing else than continuous endeavor; for when endeavor ceases, motion ceases, and therefore there is nothing essential in motion except endeavor. The learned know this, for it is an acknowledged and confirmed theorem. Endeavor in man is will, and motion in him is action; they are so called in man because in him endeavor and motion are living. To be judged according to the will is the same thing as to be judged according to the love, and also the same as to be judged according to the ends of life, likewise to be judged according to the life, for the will of man is his love, and is his end of life, and is his very life itself. That this is the case is evident from the words of the Lord quoted above, that "whoever looketh on a strange woman to lust after her hath committed adultery with her already in his heart" (Matt. 5:27, 28);
