And then you quote James 2:14-26 as what faith looks like.
Yes, that is what faith looks exactly like. To the twelve tribes who are scattered abroad. That James wrote his epistle to. Who are going through the tribulation. The same group of people who Hebrews was written to. The Hebrews. And the books of John 1, John 2, Jude, and Revelation. They are tribulation saints who are enduring to the end to go into the Kingdom that will be established upon Christ's 2nd coming.
We know (or SHOULD know where we are in God's Plan for mankind. We know that our gospel, our salvation, or faith is to be found in this present dispensation of the grace of God. The "BUT NOW" of Ephesians.
We know that the "Time Past" of Ephesians was before the Church the Body of Christ was formed, and the Kingdom promises were in effect for a group of kingdom believers. The Little Flock.
And we know that the "Ages to Come" in Ephesians must refer to the time AFTER the dispensation of the grace of God ends, the "But Now" period we are living in.
Where will those future believers in Christ as their Messiah go in God's Word to find their instructions from God for their part of God's Plan for mankind? It can't be in Romans through Philemon. It's for their understanding, but they cannot escape the coming wrath of God, the tribulation, that we are promised to be saved from. So where do they go for their survival manual? From Hebrews to Revelation. That will give them God's Word to THEM. They must endure, they must produce fruits meant for repentance, they must follow Christ as He has instructed them in those books, looking for His eminent return to set up the Kingdom promised them.
All the Bible is for our understanding. But there are certain parts that are for a certain group of people, their "private mail" from God for instructions to them in particular. That is what dispensational, rightly dividing God's word is about. Find where you are, and find what God is expecting for you in His plan.
I hesitate to ask, but...is Jesus's teaching about the Kingdom of Heaven therefore not relevant, applicable, to everyone, us?
I don’t agree that there are separate gospels or that parts are only for others.
I don’t understand all of the dispensational beliefs, but I know that there is One Lord and God of all, One faith and one baptism.
There is before Jesus and after Jesus, nothing else.
The gates of heaven was closed to us, after Jesus it is opened.
