No, you are wrong. No man. Period. You are a “man.” It says no man, that includes you.
No one can take you from God. Your everlasting rewards will not be what they could have been and your walk on earth will not be blessed as it should have been, but no one, including yourself, can remove you from salvation.
After salvation, it is not meant for you to live in constant fear that you will lose your salvation. It is meant for you to grow in a walk with Christ, to experience peace, to be a light for Him in this world of sin.
I agree, this is a major point of Christ's message contrary to judaism of the time.
However we should not be complacent, not presume we have God in a box no matter what we do, think or believe; that no matter how much we sin, how many we hurt, whether we believe in God or not, whether we choose to walk with evil, that we need not repent or ask forgiveness; that even if we no longer trust in God, even if we no longer believe in God, He will save us because once we did or thought we did.
It is not an either/or: constant fear or OSAS. Neither is biblical or what Christ taught.
No man. Period. You are a “man.” It says no man, that includes you.
That's an odd and relatively modern interpretration. I wonder: Do you maintain that you can choose to follow Christ, but you cannot choose later to not follow Christ? A one time choice without another? Or do you argue that you didn't/don't have a choice either way?
