I am left with the distinct impression that like so many others, you simply refuse to address divisiveness as a sin. I don't think God sent Paul to denounce what God was doing.
But maybe your hope is tragically misplaced, maybe your conversion is spurious, as you guys love to claim regarding any who disagree with you. As you guys say, were that to be unhappily the case, you would only get what you deserve.
You guys take too many pages from the Pharisees' playbook:
Luke 18:11,13,14
11 The Pharisee stood and prayed thus with himself, God, I thank thee, that I am not as other men are, extortioners, unjust, adulterers, or even as this publican.
13 And the publican, standing afar off, would not lift up so much as his eyes unto heaven, but smote upon his breast, saying, God be merciful to me a sinner.
14 I tell you, this man went down to his house justified rather than the other: for every one that exalteth himself shall be abased; and he that humbleth himself shall be exalted.
The difference between the faithful and the reprobate is that the faithful obey the Gospel -- faith in the Lord Jesus Christ, sincere repentance, baptism for the remission of sins, keeping the commandments, enduring in faith to the end, building Christlike character, living a life of service, doing what Jesus tells us to do, as the prophets teach us in the Scriptures.
Ephesians 2:8
8 For by grace are ye saved through faith; and that not of yourselves: it is the gift of God:
Romans 10:16
16 But they have not all obeyed the gospel. For Esaias saith, Lord, who hath believed our report?
2 Thessalonians 1:8
8 In flaming fire taking vengeance on them that know not God, and that obey not the gospel of our Lord Jesus Christ:
1 Peter 4:17
17 For the time is come that judgment must begin at the house of God: and if it first begin at us, what shall the end be of them that obey not the gospel of God?
The Lord gives us all the ability to repent, and offers His eternal opportunities to all, on condition of obedience to His Gospel: faith in Christ, repentance, etc.
God bless you!
