If those who have accepted Christ as their personal savior are forever saved in spite of their subsequent conduct, please explain the following scripture which seem to say that those who sin after they know of Christ are condemned, and are worse than the unbeliever.

“By the which will we are sanctified through the offering of the body of Jesus Christ once for all. And every priest standeth daily ministering and offering oftentimes the same sacrifices, which can never take away sins: But this man, after he had offered one sacrifice for sins for ever, sat down on the right hand of God

For by one offering he hath perfected for ever them that are sanctified Whereof the Holy Ghost also is a witness to us: for after that he had said before, This is the covenant that I will make with them after those days, saith the Lord, I will put my laws into their hearts, and in their minds will I write them; And their sins and iniquities will I remember no more.

Now where remission of these is, there is no more offering for sin. ….For if we sin wilfully after that we have received the knowledge of the truth, there remaineth no more sacrifice for sins, But a certain fearful looking for of judgment and fiery indignation, which shall devour the adversaries.”
- Hebrews 10:10-27

"For if after they have escaped the pollutions of the world through the knowledge of the Lord “and Saviour Jesus Christ, they are again entangled therein, and overcome, the latter end is worse with them than the beginning.

For it had been better for them not to have known the way of righteousness, than, after they have known it, to turn from the holy commandment delivered unto them. But it is happened unto them according to the true proverb, The dog is turned to his own vomit again; and the sow that was washed to her wallowing in the mire”
- 2 Peter 2:20-22
