And He may even require them to stay within those churches to spread His Good News where it is needed.

If you read the scriptures, you'd see that this doesn't ring true.

Be ye not unequally yoked together with unbelievers: for what fellowship hath righteousness with unrighteousness? And what communion hath light with darkness? And what concord hath Christ with Belial? Or what part hath he that believeth with an infidel? And what agreement hath the temple of God with idols? For ye are the temple of the living God; as God hath said, I will dwell in them, and walk in them; and I will be their God, and they shall be my people. Wherefore come out from among them, and be ye separate, saith The Lord. (2 Corinthians 6:14,17a.)

All scripture is given by inspiration of God and is not self-contradictory. We can witness and share the gospel with unbelievers, but we are commanded to not forsake the gathering of the saints.

I seriously doubt the wisdom of one who does so. The church is for the equipping of the saints to share the gospel. Those who don't go to church, aren't soul winning.

And yet Jesus went out among the sinners continuously.

The scriptures you are using relate generally, and some specifically, have to do with those caught in a known sin, and knowing it. In fact, there is a three step process described in the New Testament for dealing with those who HAVE KNOWN God but are sinning.

There is no straight line between your point and the scriptures you have presented.

We are to go where the sinners are, and there are very few concrete and defined reasons for not doing that.

As an example, I would present John Wesley, who presided over the greatest Holy Spirit driven revival that Great Britain has ever seen. He started his own Church organization that became known as the Methodist Church, all the while holding his membership in the Church of England, and all the while commenting what was wrong with the Church of England. And yet, even while doing what You might classify as unscriptural, God blessed his ministry with hundreds of Thousands, if not millions of souls that were born again.

God does not bless those who are disobeying him.
