You do not decide which columns do or don’t need excerpting.
You are either saved, never saved, or backslid. This bunk about “fallen out of fellowship with God” but nonetheless still saved has led to people making a license to sin out of grace and led to a plethora of sins, just like Roman catholic doctrine has led to a plethora of sins and a making a license to sin out of grace.
Baptists, etc, say “I shouldn’t gamble or drink, but I am going to do it anyway this weekened” but I am still saved, for example. I have heard this myself on gambling and drinking.
Just because some misuse the doctrine does not invalidate it.
When we are saved, we are sealed with the Holy Spirit until the day of redemption. He is the guarantee of our redemption.
We are seated with Christ in the heavenly places and God has (past tense) transferred us into the kingdom of the Son he loves.
Sin breaks the fellowship, but does not break the relationship. Your children do not cease to be your children when they disobey you. In the family at one minute and out the next.
No, the child is still the child, even when breaking the parent's hearts.
There certainly will be loss of reward for sin, and repercussions, even here on earth, but God knows our frame and remembers that we are dust. HE knows we're weak and fail and fall.That's the beauty of His mercy and forgiveness.
If we had to earn His forgiveness, it wouldn't be mercy and grace, it would be wages due for behavior performed.
