2 Peter 2:1-3, 10-15 & 17-21 But there were also false prophets among the people, just as there will be false teachers among you. They will secretly introduce destructive heresies, even denying the sovereign Lord who bought them—bringing swift destruction on themselves. Many will follow their depraved conduct and will bring the way of truth into disrepute. In their greed these teachers will exploit you with fabricated stories. Their condemnation has long been hanging over them, and their destruction has not been sleeping. ... Bold and arrogant, they are not afraid to heap abuse on celestial beings; yet even angels, although they are stronger and more powerful, do not heap abuse on such beings when bringing judgment on them from the Lord. But these people blaspheme in matters they do not understand. They are like unreasoning animals, creatures of instinct, born only to be caught and destroyed, and like animals they too will perish. They will be paid back with harm for the harm they have done. Their idea of pleasure is to carouse in broad daylight. They are blots and blemishes, reveling in their pleasures while they feast with you. With eyes full of adultery, they never stop sinning; they seduce the unstable; they are experts in greed—an accursed brood! They have left the straight way and wandered off to follow the way of Balaam son of Bezer, who loved the wages of wickedness. ... These people are springs without water and mists driven by a storm. Blackest darkness is reserved for them. For they mouth empty, boastful words and, by appealing to the lustful desires of the flesh, they entice people who are just escaping from those who live in error. They promise them freedom, while they themselves are slaves of depravity—for “people are slaves to whatever has mastered them.” If they have escaped the corruption of the world by knowing our Lord and Savior Jesus Christ and are again entangled in it and are overcome, they are worse off at the end than they were at the beginning. It would have been better for them not to have known the way of righteousness, than to have known it and then to turn their backs on the sacred command that was passed on to them.What "sacred command" is Peter talking about? That is to believe on the Lord Jesus Christ and commit to obeying His precepts. A few of those are listed in the fruits of the Spirit, one of which is self-control. "Slain in the spirit" is an occult method to get people out of self-control and under the control of another spirit. Be care of "feasting" with these people who are "carousing in broad daylight" and doing everything Peter talked about in the above passage.
