Ya when a saved person falls into sin, God has truth mixed with grace in treating that sin. His truth.. this sin is hurting God, and there are consequences that the saved person is going to have to go through.. but God has forgiven their sin in advance by His payment for them.. His sacrifice for them on the cross.
So... they will be disciplined and rebuked.. but this is undergirded by a commitment from God to stay with us through thick and thin.
Rev 3:19 As many as I
love, I rebuke and chasten: be zealous therefore, and repent.
This is perfect parenting
Now.. if you get a local church family being generally unfaithful.. the Holy Spirit will then start rebuking and discipling the whole assembly through convicting the leadership of that church and the congregation. If they continue in going off beam.. the Holy Spirit can remove His presence as the Comforter from that church.. and it no longer stays as one of His own assemblies.
Rev 1:20 The mystery of the seven stars which thou sawest in my right hand, and the seven golden candlesticks. The seven stars are the angels of the seven churches: and the seven
candlesticks which thou sawest are the seven churches.
To one of the churches:
Rev 2:5 Remember therefore from whence thou art fallen, and repent, and do the first works; or else I will come unto thee quickly, and will remove thy
candlestick out of his place, except thou repent.
So.. the Holy Spirit can remove His authority from a church family to be one of His own -
they don't lose salvation.. but can lose authority due to unfaithfulness.
Again.. grace and truth mixed.. the unfaithfulness not leading to the consequence of being cast into hell, but a church family losing their authority to be one of His.
