Yes once saved always saved is biblical.
John 6:40
"For my Father's will is that everyne who looks to the Son and believes in Him shall have eternal life, and I will raise him up at the last day."
John 10:28-29
"I give them eternal life, and they shall never perish; no one can snatch them out of my hand. My Father, who has given them to me, is greater than all; no one can snatch them out of my Father's hand. I and my Father are one."
Do you think that if a rock had fell on Peter right after denying Jesus that he would have went to hell? Do you think that the most loyal of the Lord's followers, if he/she were to slip up and say a curse word as they wreck and die that they will go to hell after their loyalty to the Lord all their reborn life?
I believe people that claim to have been a Christian that now claim not to be are one of two things: 1. Either they never really knew the Lord to begin with, or 2. They are a wayward child of God.
I honestly don't believe that you can turn your salvation on and off like a light switch. There are so many Christians that I know (particularly new Christians) that are afraid they will "loose" their salvation. The bible says to be saved is to be dead to the old man and raise a new creature, does that mean we can choose to resurrect the old creature? Christians aren't sinless, we sin less, that's from walking with the Lord. But all have sinned and fallen short. None of use can be what Jesus was and is. If we were able to live perfect lives Jesus would not have had to live a perfect sinless life and die a torturous death for us.
I think the whole idea of "loosing ones salvation" is a tool of the enemy to keep us chasing our tails instead of doing the work the Lord would have us to be doing. The Lord is strong even when we are weak. How can we tell others about His strength and greatness if we don't believe Him even strong enough to keep us as His, after we have freely given ourselves to Him?
Do you believe in absolute truths? If not, maybe you should be reconsidering if you honestly believe in the Lord. If so, how can you question God's greatest gift and truth?
Ummm I get little passionate about this
