Hello Bob,
The twelve tribes names (jacob/Israel sons) correspond IMHO to the traits we gain approaching Jesus and learning to know the true God, Our Father. I wrote a thread about it:
https://bible-truths.com/forums/index.php/topic,17152.msg155979.html#msg155979Matthew 19:28 makes me think about Revelation 3:21:
« Those who are victorious will sit with me on my throne, just as I was victorious and sat with my Father on his throne. »
In Matthew v28 as in Revelation v21, there are aorist tense verbs. Ray taught us it reveals a process in progress, something that keeps on happening, for a time, for an age.
We are being victorious by judging our own flaws, being able to recognize them clearly (Paul in Romans says that sin must appears as « excessively » sin).
How do I worship my Father? In a way that pleases Him? How do I see His Holiness? What about mine? I would say that the twelve tribes of Israel are within us, the heart of our hearts, we are being our own judges, the grace of God guides us through Christ, opening our eyes, our mouths, our minds a little more each time.
In 1 Corinthians 6:2-3, Paul says:
« Or do you not know that the Lord’s people will judge the world? And if you are to judge the world, are you not competent to judge trivial cases? 3 Do you not know that we will judge angels? How much more the things of this life »
We are to become later judges of this world, according to the will of God, but first we must learn to get rid of all of the flaws that are inside of us thus in our lives: Matthew 7:3 « Why do you look at the speck of sawdust in your brother’s eye and pay no attention to the plank in your own eye? »
Tests give us more and more discernment so that we can please God and serve Him better. We should ask ourselves, in every step of our spiritual way, the question Paul asks in galatians 1:10:
« Am I now trying to win the approval of human beings, or of God? Or am I trying to please people? If I were still trying to please people, I would not be a servant of Christ » IMHO
