(I send this forth in all sincerity and with the kindness of Christ. If you disagree, please respond graciously also. God’s people should be able to have a serious and Christ-honoring discussion about this hotly debated subject. Thank you.)
Let me set the table with something the Lord Jesus said. When the disciples returned from preaching with glowing reports of amazing victories over the devil, our Lord called them back to earth, so to speak, with this:
“Do not rejoice because the spirits are subject to you. But rejoice because your names are written in heaven” (Luke 10:20).
Now, look at what He did there. The Lord changed the basis of their joy and thanksgiving from something that fluctuates–like the outward results of missions, which can be good or bad, up and down–to something permanent and unchanging, our salvation.
The Lord Jesus clearly thought our salvation was secure. And He should know, right?
Otherwise, wouldn’t He have chosen some other basis for our joy?
No other conclusion is possible. Jesus clearly thought salvation was a once-and-done proposition. Something permanent, solid, irreversible.
As far as I am able to tell, you will not find one place in the utterances of the Lord Jesus that say otherwise.
For those who find they cannot accept the teaching of “once saved always saved” (aka, the security of the believer), we have a few questions….
