There's Still Hope for All of Us:
My process of repentance continues. In a public forum, I refuse to include anyone by name into any particular group. Final Judgement is the Lord's responsibility, not ours. While we are still under probation, we can still repent and still forgive, so we can choose to repent and change groups any time we want to, so long as our probation continues.
Unless our Eternal Election has been sealed by the Holy Spirit of Promise, it's never too late to repent, to change course, and to decide to be better and think better. Even then, we will still have agency. Cain can still choose to do good if he actually wants to do good and be good, even though his appointment with Outer Darkness has already been sealed upon his head.
There was a time when Cain was a member of the Church of Jesus Christ, but he chose to leave that group and join another group. It was his choice. Nobody made him do it. Cain committed murder after having his Calling and Election Made Sure; therefore, Cain became a Son of Perdition and had Outer Darkness sealed upon his head instead. But, Cain can still choose to do good if he wants to.
If we can choose to leave the Church of Jesus Christ and abandon God's Apostles, then we can also choose to join the Church of Jesus Christ in our hearts and in deed, and choose to sustain the Apostles of God. Before the Final Judgment, it's never too late to repent and make that choice, unless we go so far in the hole as to have Outer Darkness sealed upon our heads instead.
There's still hope for all of us, unless some of us have already had Outer Darkness sealed upon our heads.
