Under the new covenant faithful ministers of God must likewise warn those in their congregation, who are living unrighteous lives that they will be excluded from God's kingdom and salvation if they do not repent.
In I Corinthians 6:9 we see where some of the people we deceived into believing that even if they broke fellowship with Christ,disowned him and lived in immorality and injustice in God's kingdom were still secure.
HOWEVER: Paul declares that spiritual death is the inevitable consequence of habitual sinning, even for the Christian.
NO ONE CAN LIVE IMMORAL LIVES AND STILL INHERIT THE KINGDOM OF GOD.
Romans 8:13 For if you live according to the sinful nature, you will die; but if by the Spirit you put to death the misdeeds of the body, you will live.
In the 8th chapter of Romans Paul emphasizes the necessity for continual warfare against all that limit God's work in our lives for sin is always striving to regain control over us. This spiritual conflict force is primarily "our flesh".
We as believers must continually decide whether we will surrender
to the flesh the sinful desires
Or to the demands of the divine nature in which we participate in
following of the Holy Spirit.
In Galatians 5:19-21 it clearly states what a sinful nature is. Sexual immorality, impurity, debauchery, indecency, idolatry, witchcraft, hatred, discord, jealousy, dissensions,and division. Envy drunkenness, carousing and the like. I warn you beforehand just as I did before that those who do such things shall not inherit the kingdom of God.
As you can see the results of failing to put to death the misdeeds of the body, the desires of the flesh, are spiritual death and the loss of your inheritance in God's kingdom.
Now listen to this: In Romans 8:13 the words "you will die means
that a Christian can pass from spiritual life back into spiritual death.
Thus, the life of God that we receive at our new birth can
Be extinguished in the soul of a beliver who refuses to put to death
the misdeeds of the body!
Therefore you can truly take this fact to the bank: If one is consistently putting to death the misdeeds of the body, then the Spirit of God is leading them. Those led by the Spirit of God are truly God's children.
Those who teach that believers may live immoral and unrighteous lives without jeopardizing their eternal salvation will thethemselves face God's sever judgement.
We as belivers muest always remember this: God has given us the commission tog into all the world and proclaim the gospel.
Matthew 28:18-20: " All authority in heaven and on thee earth has been given to me. Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and the H9ly Spirit. Teaching them to obey everything I have commanded you: For surely I am with you always to the very end of the age."
But always remember this that this commission also includes a Big Warning in Big Bold Letters:
ETURNAL DEATH FOR ALL WHO REFUSE TO REPENT AND BELIEVE IN CHRIST.
