If you choose to reject the Gospel, you are condemned.
Rejecting and backsliding/or being lazy are different things.
Recently a Southern Baptist friend told me you could only accept/have a chance at a relationship with the Lord once.
She quoted Hebrews ch 6 as proof of this. I asked about the prodigal son. She replied that the prodigal son was unsaved. You have to have some place to leave.
Through God's grace we are saved from ourselves. Repeatedly.
