Many of the passages you used were taken out of context and were about the lost not the saved.
Show me where I have taken any Scripture out of context.
Semantics! They have lost fellowship with the Lord. If you quarrel with a friend, and no longer feel at ease with him, you are not "in fellowship" with him. And you won't be until your problem is resolved. The same is true with the Lord.No Christian can ever lose fellowship. If a Christian has something in their life they are not gaining victory over and they are not feeling the sweet joy (fellowship) of the Lord the fellowship is not broken it has simply turned to an unpleasant fellowship.
You are just playing a game of semantics. Just try it. You will be chastised by the Lord. He will never leave you, that is true. But you won't be in fellowship with him either. You won't have the freedom to go right before his throne of grace until that sin is cleared up.The proof is just try and sin another sin and see what happens as the conviction increases. Fellowship is never broken for a believer.
If you study the Book of Hebrews, that is the sin that the author was dealing with--backsliding Jewish Christians who were thinking of returning to the OT Covenant. Think about it? Who would leave our Great High Priest, the Lord Jesus Christ with all the daily blessings he provides us with, and want to return to an old system with frail human priests that must stand and offer daily sacrifices. Which system has the greater benefit? And yet these Christians were at the point of going back. Why? Persecution had gotten them so discouraged they were backslidden and on the verge of going back to Jerusalem where the OT system of worship was still being practiced.The problem you are having is that you believe a Christian can backslide into sinning which the bible denies can happen.
That is a nice story, but where do you get it from. Not the Bible. Where do you get this "programed into thinking they are saved," business? Who taught you that? Either a person is saved or he is not. And a saved person can sin; and if he does sin he can lose fellowship, but not salvation.That person never had fellowship to start with, but because of a false profession, cleaning up their own life on the outside to some degree, and being surrounded by real Christians, they thought they had fellowship although all they had was a shadow of the reality. When this person who is really lost departs back into their sinning (2 Peter 2:22) they are left with the reality of what they are, lost with no fellowship, but because they have been programed into thinking they are saved because of false teachings of backsliding they think they just lost fellowship which they never had.
"If I regard iniquity in my heart the Lord will not hear me."
That is a loss of fellowship.
Sin breaks our fellowship with God everytime.
We need to restore it by confession of sin. It is the only way.
There is no verse in the Bible that teaches that.NO true believer can lose fellowship.
