See in your own words here, the answer.
God does explain / He Reveals also, how they are His people even with the problems you have noted.
The impurity you see in Corinthians chapters, is a million-fold on the internet worse,
yet you are participating yourself in such a place, right? And still you are/ may be/ pure yourself , right ? Most people are never born again, never pure, as written in Scripture "all have gone astray" and they are not even seeking to do good. So with all who have gone astray, have you gone astray therefore? God Forbid! Once yes, we all were gone astray, but thanks be to Jesus Who Himself was once sacrificed for our sin, we may have fellowship one with another and IN Christ Jesus our Lord and Savior TODAY..... although it is with many difficulties and impure ones, even many antichrists today... our only hope is in Jesus.
Gotcha, or at least I THINK I understand what you're talking about. Romans chapter 3 deals with those who follow the Law of Moses in order to obtain Righteousness. Therefore, none under the Law can be considered Righteous because it was a temporary guarding to protect them until Christ came. Romans 3:22 talks about the transition from the Law to Christ, in that Righteousness comes by Faith in Christ alone. Hence, because of this Spiritual Righteousness, Blessed Jews and Gentiles can both obtain this Righteousness.
What I know is that Jesus the Purpose of Jesus is to Redeem His Elect from the Curse of the Lord, the Curse that the Law makes known in how that Curse causes people to disobey.
Galatians 3:13 NLT - "But Christ has rescued us from the curse pronounced by the law. When he was hung on the cross, he took upon himself the curse for our wrongdoing. For it is written in the Scriptures, "Cursed is everyone who is hung on a tree."
As for me, I didn't "go astray," for I was always "astray" until I Powerfully received the Holy Spirit and Spiritual Circumcision in one remarkable moment while in the Arizona Desert. From that unbelievable day and forward, I have been Transformed Spiritually and continue to Transform to this day through Holy Sanctification. I received the same Promises and Blessings that Abraham, David, Joshua, Caleb, Rahab, and many others received.
Like Moses said, I wish that all people had the Holy Spirit as a Leader and Guide, for when this gift and Promise is given, it becomes undeniable that we are now held captive by God with the express Purpose to not only obey, but spread His unbelievable message. Just as we are compelled to obey, we are also compelled to learn the actual Gospel AND the Saving Plan of Jesus Christ. When a person is released from the Curse, when they are no longer under the "Power of sin," that person is emotionally and Spiritually free . . . they are not the same anymore. Yet, until a person experiences this, it cannot be understood. For, all "christians" say that they are Saved, yet who and how many of all "christians" can testify of a Transformation that renders them powerless to control the outcome of their lives?
Spiritual Circumcision is very much like waking up from a dream. We don't know that we're dreaming until we wake up. This is the problem with most "christians" of today . . . they do not realize that they are asleep anymore that did the Pharisees, Sadducees, and teachers of the Law during the Day of Christ.
Luke 11:35 NLT - "Make sure that the light you think you have is not actually darkness."
Who is "making sure?" If we don't know the Story of God AND the Saving Plan of Christ, a person is incapable to making such a determination.
Have a Blessed day, Dan!
