There is a massive difference between church discipline to protect the people and the Lord sending you to hell as can be seen by the letter Paul said to the 1 Corinthians.
Paul told them who they were in Christ...then corrected their behavior...he didn't say you were all unsaved now or that because they were sinning that they were not born of God like some people try to teach.
Or that their loving Father will now throw them in the lake of fire. What total religious nonsense and that is straight from the enemy to get us to doubt the love, grace of God for us and for us to rely on our own self-efforts of works-based righteousness.
( without understanding the new creation in Christ - this "sinning" part will throw people off because they don't understand what is being done by giving in to the flesh and what the new man is Christ really is. )
Paul told them who they were in Christ...Here are 7 things that Paul confirmed as truth in the believers in Corinth before he went on to correct their behavior.
1) The Corinthians have been sanctified in Christ Jesus,
2) The Corinthians were now saints by calling
3) The Corinthians in everything were enriched in Him,
4) The Corinthians had the testimony concerning Christ was confirmed in them,
5) The Corinthians had that God will also confirm them to the end, blameless in the day of our Lord Jesus Christ
6) The Corinthians had that it was by Gods doing that we are in Christ ( Not our own D.I.Y. self-righteousness and holiness )
7) That because the Corinthians were in Christ - Christ Himself became to them wisdom from God, and righteousness and sanctification, and redemption
1 Corinthians 1:2-9 (NASB)
[SUP]2 [/SUP] To the church of God which is at Corinth, to those who have been sanctified in Christ Jesus, saints by calling, with all who in every place call on the name of our Lord Jesus Christ, their Lord and ours:
[SUP]3 [/SUP] Grace to you and peace from God our Father and the Lord Jesus Christ.
[SUP]4 [/SUP] I thank my God always concerning you for the grace of God which was given you in Christ Jesus,
[SUP]5 [/SUP] that in everything you were enriched in Him, in all speech and all knowledge,
[SUP]6 [/SUP] even as the testimony concerning Christ was confirmed in you,
[SUP]7 [/SUP] so that you are not lacking in any gift, awaiting eagerly the revelation of our Lord Jesus Christ,
[SUP]8 [/SUP] who will also confirm you to the end, blameless in the day of our Lord Jesus Christ.
[SUP]9 [/SUP] God is faithful, through whom you were called into fellowship with His Son, Jesus Christ our Lord.
1 Corinthians 1:30 (NASB)
[SUP]30 [/SUP] But by His doing you are in Christ Jesus, who became to us wisdom from God, and righteousness and sanctification, and redemption,
Preach and teach the grace of Christ as it is the only think that teaches us how to live godly in this world. Titus 2:11-12. The word of His grace is the only thing that is able to build us up and that gives us the inheritance that is ours in Christ. Acts 20:32
