He cuts off every branch in me that bears no fruit |
If you do not remain in me, you are like a branch that is thrown away and withers; such branches are picked up, thrown into the fire and burned. |
If you keep my commands, you will remain in my love, |
The problem with such an interpretation is that every sin removes us from Him, and every man is a sinner, even after faith in Christ. There is only one sacrifice, so if it were possible to lose salvation, even after one sin, the group of humans who are saved would only have one member, namely Christ.
On the contrary, it is possible to be saved as a believer, and upon sin after salvation, we simply are removed from fellowship with Him. That post-salvation sin is then forgiven after we face God in repentance, and confess the sin to Him per 1st John 1:9.
He provides life in the spirit and when we fall out of fellowship, we might be acting soulishly, but not spiritually.
If we keep His commands, we remain in His love.
