Some erroneously teach, in my opinion, that a saved regenerated believer in Christ can lose his salvation and become un-born-again, unregenerate, through some action on his or her own part. While discussing this one day with a Christian brother, who believes such is possible, I asked him for a biblical text in support of the idea. He gave me 2 Peter 2:19 and 20.
While they promise them liberty, they themselves are the servants [slaves] of corruption: for of whom a man is overcome, of the same is he brought in bondage [enslaved]. 20 For if after they have escaped the pollutions of the world through the knowledge of the Lord and Savior Jesus Christ, they are again entangled therein, and overcome, the latter end is worse with them than the beginning.
Reading that passage it does almost seem to support such a notion, except when you put it in its original context. And also it brings up a concept centred on the meaning of the word ‘overcome’ as used in the Bible. Since we are admonished (2 Timothy 2:15) to rightly handle the word of truth, let’s look into this matter a little more. (All bold are my emphases added. Square brackets [ ] indicate meanings of words. King James Version Easy-Reading Bible (KJVER) used.)
2 Timothy 2:15 Study [Be diligent] to show yourself approved to God, a workman that needs not to be ashamed, rightly dividing the word of truth.
The Authorized version uses the word ‘dividing’ which I believe captures the point very precisely. We need to divide truth from error.
