The most frequently used argument given by the proponents of eternal security is a total misuse of John 10:28. Follow along carefully and it will become apparent how the eternal security teachers have distorted that Scripture. John 10:28 reads:
I give them eternal life, and they shall never perish; no one can snatch them out of my hand.
By avoiding the immediate context of verse 27 — which identifies who gets eternal life, will never perish and can’t be snatched from Jesus’ hand — the eternal security teachers are able to conceal to WHOM Jesus was referring! The context exposes their serious error. Verse 27 reads:
My sheep listen to my voice; I know them, and they follow me. (John 10:27)
In other words, Jesus is teaching it is the sheep —described as those who listen to his voice, are known by him and especially they follow him (continuous tense) — who will never perish and will not be plucked from his hand. They are the ones given eternal life. But that is not the way John 10:28 is taught. The eternal security teachers have misused John 10:28 to allow for unrepentant backsliders to have eternal life, when it not only doesn’t fit the context, it is the opposite of what Jesus taught there and other places! Again, backsliders are not following Jesus! They are not his sheep. Therefore, John 10:28 does not apply to them.
To misuse John 10:28 to teach once saved always saved, as often done in our day, is to give a dangerous false sense of salvation to lost people, who desperately need to repent, but are convinced they are still in relationship with God.
NOTE: The license to sin teachers are dangerous blind guides. Do NOT be deceived by their Scripture twisting to allow for wickedness, as listed in 1 Cor. 6:9,10 and Rev. 21:8, and salvation at the same time. Sin has pleasure for a short time, but it will drag you to hell. It is still the issue! God bless you.
