WHY ??
You cannot have wilfully sinful people inside a church body that is committed to upholding and living to the righteousness
of God.
Read your Bible for in both the OT and the NT it states put out the wicked man from among you.
And yes when church members separate or divorce then they too need to be put out, and the whole failure sorted out
to the resolution of those involved, and to the continued wholesomeness of the church.
The gospel is for us to repent and embrace salvation leading to us living righteously for God our new Lord in life.
Those who continue in sinning are serving their old Lord - Satan.
maybe you chose your words poorly
are you suggesting you havent sinned since being made new?
there is a huge difference from never getting a new heart
and calling good evil and evil good
(reprobate... not born again)
and the flimsy grace, revolving door theology based on your walk maintaining salvation
that is a false works gospel for men seeking to establish their own righteousness (everyone who does not recieve the imputed righteousness of Jesus will not make it)
to think someone who has come to Christ as a homosexual through the searing of their heart towards lust
will instantly overcome even facing any temptation in the future and even failing once (even only in thought) means they are not born again
that would be ridiculous
God is more than powerul enough to not only deliver them from temptation but change their desires
but this happens through a new heart
quickened spirit
followed by prayer and a relationship with our father
we arent born again as a fruitful tree
we are born again as sapplings
then through HIM working in us (He will chasten us for our failures and encourage us in our victories which He produces ultimately) that our paths are straightened
but you arent saved when you "stop sinning"
you are saved when you TRUELY believe in Christ
this type of genuine faith is followed by the gifts of God through HIS work
(including fruit)
