Actually, isn't it referred to as "the doctrine of OSAS"? Teaching is a synonym for Doctrine.
So, when we accept Christ, from that moment on, we're locked in. OK, let's ask John what he thinks:
"Let that therefore abide in you, which ye have heard from the beginning. If that which ye have heard from the beginning shall remain in you, ye also shall continue in the Son, and in the Father." - 1 John 2:24
Cast aside that which previously remained in you from the beginning and it's a one way ticket to the Resurrection of the Damned.
There is no Spiritual Switzerland.
You're either a branch connected to the vine, or you're in the fire.
You're either a sheep of His fold, or the wolf will eat you.
You're either a lost Prodigal or a found son...a dead Prodigal or a live son.
You're either with Him or against Him.
OSAS wants desperately to find in the Bible a mythological third category of faith (like the one Charles Stanley preaches called the "carnal Christian") where we can be out of "fellowship" with God without danger of Satan filling the vacuum. We all know what happens when the devil finds a swept and garnished but empty house, right?
The only "works" I preach is "faith which
worketh by love" - Galatians 5:6
For you and those who preach the dead faith of OSAS, I say eternal life can only be obtained by practicing living faith in Jesus - "faith which worketh by love".
