Sexual promiscuity and sexual perversion were grounds for exclusion from the community of Israel.
Is it grounds for exclusion from spiritual Israel (the BodyOfChrist)?
The specific sin of fornication (whether heterosexual or homosexual) has been forgiven for the perpetrator through the blood of Christ Jesus.
However repentance is needed to appropriate that forgiveness. The most significant sin to be repented of is SelfWorship. A person who worships themself will not turn loose of thinking and behaviour which violates the law of the Lord.
The Lord receives those who come under His Lordship. Satan rejects the Lordship of Christ Jesus and so does every ChildOfSatan.
There is forgiveness for our past when we nail it to the cross of Christ Jesus.
Those who receive Christ must also receive His Word.
