Don't be ignorant. The "once saved always saved" is a false doctrine. Jesus Himself warned us of the great falling away from the faith. I believe in Phillipians 2:12 - "Wherefore, my beloved, as ye have always obeyed, not as in my presence only, but now much more in my absence, work out your own salvation with fear and trembling." Hebrews 6 is unequivocal about this; it says from the 4th verse of Hebrew 6 "For it is IMPOSSIBLE for those who were once enlightened (saved), and have tasted of the Heavenly gift, and were made partakers of the Holy Ghost,
5*And have tasted the good word of God, and the powers of the world to come,
6*If they shall fall away, to renew them again unto repentance; seeing they crucify to themselves the Son of God afresh, and put him to an open shame."
The Bible is full of people who were once Saved but fell away from The Faith -
I don't believe in the "Once Saved Always Saved"; I will go even further to say that it is a dangerous doctrine. In Acts 5, we read about Ananias and Sapphira his wife "5*But a certain man named Ananias, with Sapphira his wife, sold a possession. 2*And he kept back part of the proceeds, his wife also being aware of it, and brought a certain part and laid it at the apostles’ feet. 3*But Peter said, “Ananias, why has Satan filled your heart to lie to the Holy Spirit and keep back part of the price of the land for yourself? 4*While it remained, was it not your own? And after it was sold, was it not in your own control? Why have you conceived this thing in your heart? You have not lied to men but to God.”
5*Then Ananias, hearing these words, fell down and breathed his last. So great fear came upon all those who heard these things. 6*And the young men arose and wrapped him up, carried him out, and buried him." Lastly but not the least, we all know the story of Judas Iscariot who betrayed Jesus. Would you say he, Judas was once saved? I do not believe in the "Once Saved Always Saved " doctrine and believe it is a very dangerous doctrine.
