Let me ask you again...Have you been reconciled to God?
Because if you have been reconciled, do you deny Romans 5:10 as being God's Word?
Our choices are shaped by our desires. Do you believe that through the new birth, a Christian would desire to walk away?
I genuinely believe a Christian born of the spirit would desire to walk away.
They may struggle with sin, they may even wander off the level path become a sheep.
Sheep are herd animals. They do not tend to wander off but they can do.
It can be bacause they are in pain.
One thing I know is that a sheep on its own is a frightened sheep and it bleats.
Jesus went to look for the lost sheep because it was alone yet he left the 99 behind.
The reason being they were part of the herd and safe
So Jesus brings that sheep back on his shoulders when he finds him and he finds him because the sheep is bleating.
My guess is that the sheep does not run away but let's Jesus rescue him.
As a person with emotional pain who struggles with addictions and has wandered away I was frightened he would reject me. I was always bleating "Jesus please help me I need you"
I'm still here, never had the desire to walk away and he has always sought me and carried me back to safety.
