Be careful about being outside the camp. When we read about God's chosen people, wandering in the wilderness, we see that God lives in the midst with the 12 tribes organized around the tabernacle. People who lived outside the camp were unclean and removed from fellowship.I indeed have had a very personal and costly revelation from the Spirit of God, calling me out of organized religion, "outside of the camp" as referred to in Hebrews - which is biblical-based and not "extra-biblical".
And after this revelation, I came across others' very similar testimonies and also writings that also confirmed my renewed interpretation of Hebrews 13:13. This verse was not only asking Jews to leave the camp of Judaism in the 1st century but has come down through the centuries as a clarion call for the true ekklesia, (the called out ones), to leave the camp of churchianity -- to flee the clergy-laity, pastoral system created by men and not by the Lord.
May the Lord Himself give you this same revelation, my brother.
Hebrews 12:22-24,28
But you have come to Mount Zion and to the city of the living God, the heavenly Jerusalem, and to innumerable angels in festal gathering, and to the assembly of the firstborn who are enrolled in heaven, and to God, the judge of all, and to the spirits of the righteous made perfect, and to Jesus, the mediator of a new covenant, and to the sprinkled blood that speaks a better word than the blood of Abel.
Therefore let us be grateful for receiving a kingdom that cannot be shaken, and thus let us offer to God acceptable worship, with reverence and awe.
Notice then the reason why Jesus was outside the camp and why we follow. Jesus was killed outside the camp as our atoning sacrifice. As followers of Christ who are "in Christ" we are with Christ.
Hebrews 13:13
Therefore let us go to him outside the camp and bear the reproach he endured.
I do not think you are understanding that God calls us to be members of a local body, regardless of whether it is a house church or a local church. When we attend as members we are coming to the assembly, joining all the saints in heaven. A rogue Christian is living outside the will of God for fellowship and accountability with his brothers and sisters.
