FAQ: Can a born-again Christian lose their salvation?
A. Absolutely yes, a Christian CAN LOSE his/her salvation. This is the doctrine of unconditional eternal security or ‘once saved – always saved) that most protestant denominations teach. Just like ‘whosoever will, let him come’ – the same works for ‘whosoever wants to go, let him go’. YOU CAN FALL FROM GRACE!!! You can choose to walk away from God and his grace. Just like you had to receive Jesus Christ to get saved – you can choose to reject Christ and turn your back on Him. That is your choice and God can’t force you to remain in fellowship with Him. The Bible calls this apostasy (falling away). 1 Tim. 4:1,” Now the Spirit speaketh expressly, that in the latter times some shall depart from the faith, giving heed to seducing spirits, and doctrines of devils;…”

“For if we sin wilfully after that we have received the knowledge of the truth, there remaineth no more sacrifice for sins,…”
Hebrews 6.4-6.

“For if after they have escaped the polutions of the world through the knowledge of the Lord and Saviour Jesus Christ, they are entangled therein, and overcome, the latter end is worse with them than the beginning. 21 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. 22 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

But let me mention this, because God is all merciful and forgiving, He will still receive you back into the fold IF you repent even on your death bed. I wouldn’t take that chance though!!! You may get broadsided by a bus or a bullet from a Glock may catch up with you.

15 Looking diligently lest any man fail of the grace of God; lest any root of bitterness springing up trouble you, and thereby many be defiled ;16 Lest there be any fornicator, or profane person, as Esau, who for one morsel of meat sold his birthright. 17 For ye know how that afterward , when he would have inherited the blessing, he was REJECTED: for he found no place of repentance, though he sought it carefully with tears.
Hebrews 12:15-17
