Matthew 7:13 plus Romans 8:13
I understand, by what I have read in scripture, that the doctrine that Christ taught can be a hard saying, and difficult for some to understand, but here are some things that I have gleaned from the scriptures, according to my understanding;
Spiritual Israel, which is not all of the nation of Israel (Rom 9:6), and is made up of every kindred, and tongue, and people, and nation (Rev 5:9)
That most of spiritual Israel has turned away from God, in disobedience (Zeph 3:11), but God left in the midst of them a remnant that shall trust in the Lord, and they shall do no iniquity, nor speak lies, neither shall a deceitful tongue be found in their mouth, for they shall feed and lie down, and none shall make them afraid (Zeph 3:12-13).
By my understanding, in reading in Ezk 10, that it speaks of a wheel within a wheel, the larger outer wheel being the disobedient children of spiritual Israel, who have not lost the promise of their eternal inheritance, but have lost their fellowship with God, until they repent (Rom 11:26 - And all Israel shall be saved) I believe these to be the invisible bride of Christ, his church.
The smaller wheel being the remnant of spiritual Israel of which I believe to be the visible bride of Christ, his church.
I believe the two gates mentioned in Matt 7 harmonizes with the scriptures in Ezek 10. The wide gate being the disobedient children of God, and the strait gate being the remnant of Israel. This is one of the reasons that I believe that there will be far more that will be in heaven, than hell.
I believe the reason the wide gate leads to destruction is because the disobedient children are teaching and preaching false doctrines, and that it is the responsibility of the remnant to preach and teach the gospel to the disobedient, praying that they will repent.
Some more for you to ponder, is that I believe Paul to be a part of the remnant in Rom 10, Praying and preaching the gospel to the disobedient children, who have a zeal of God, but not according to knowledge, that they would repent.
