Gen 4, 3-7 Sin is a demon lurking at the door

(Gen 4, 3-7) Sin is a demon lurking at the door

[3] In the course of time Cain brought an offering to the LORD from the fruit of the soil, [4] while Abel, for his part, brought one of the best firstlings of his flock. The LORD looked with favor on Abel and his offering, [5] but on Cain and his offering he did not. Cain greatly resented this and was crestfallen. [6] So the LORD said to Cain: "Why are you so resentful and crestfallen? [7] If you do well, you can hold up your head; but if not, sin is a demon lurking at the door: his urge is toward you, yet you can be his master."

(CCC 2358) The number of men and women who have deep-seated homosexual tendencies is not negligible. This inclination, which is objectively disordered, constitutes for most of them a trial. They must be accepted with respect, compassion, and sensitivity. Every sign of unjust discrimination in their regard should be avoided. These persons are called to fulfill God's will in their lives and, if they are Christians, to unite to the sacrifice of the Lord's Cross the difficulties they may encounter from their condition. (CCC 2359) Homosexual persons are called to chastity. By the virtues of self-mastery that teach them inner freedom, at times by the support of disinterested friendship, by prayer and sacramental grace, they can and should gradually and resolutely approach Christian perfection.
