Are those who embrace homosexuality as their own life style the only "beasts" mentioned in the scriptures? I would certainly think not.
I would say that any man (myself most certainly included) who has not killed all of his own beasts is not yet an overcomer as Jesus was [John 16:33] and is therefore in that measure still a beasts. Many beasts were saved, in the moment, in the ark, constructed by Noah using God's design, but in the end of the matter, God has provided by now all of us with the means to kill all of our beasts and we are not pursuing this goal (killing our beasts) then we are likely feeding our beasts and keeping them healthy.
"I said in mine heart concerning the estate of the sons of men, that God might manifest them, and that they might see that they themselves are beasts. " Ecc 3:18
"Wherefore are we counted as beasts, and reputed vile in your sight?" Job 18:3
"Man that is in honour, and understandeth not, is like the beasts that perish." Psalm 49:20
"So foolish was I, and ignorant: I was as a beast before thee." Psalm 73:22
"She [Wisdom] hath killed her beasts; she hath mingled her wine; she hath also furnished her table." Prov 9:2
"As it is written, For thy sake we are killed all the day long; we are accounted as sheep for the slaughter" Rom 8:36
Have we killed all of our beasts yet? If we have not, why not? Did God not through His Son provide all that is required?
