Can I speak with you, brother regarding the issue of the kingdom here and now - as you have expressed its meaning and why you therefore refuse what you call premillennialism and dispensationalism.
So here is a start if you would like to take me up. I could even learn something myself.
Isaiah 6:9-12 would be my starting point. And Matthew 13:13-35 will be my meaning. So then having established a meaning of the kingdom of heaven, at the time of the Lord in Judea, if you can agree, we can then go on to its boundary and its character today.
Also, I would disclose that the issue is precisely a prophetic one. So perhaps we could precede Isaiah and make John 21:20-22 our prophetic anchor along with Isaiah 6:9-13 as our physical anchor.
Peter, turning around, saw the disciple whom Jesus loved following them; the one who also had leaned back on His bosom at the supper and said, “Lord, who is the one who betrays You?” So Peter seeing him said to Jesus, “Lord, and what about this man?” Jesus said to him, “If I want him to remain until I come, what is that to you? You follow Me!” John 21:20-22
He said, “Go, and tell this people: ‘Keep on listening, but do not perceive; Keep on looking, but do not understand.’ “Render the hearts of this people insensitive, Their ears dull, And their eyes dim, Otherwise they might see with their eyes, Hear with their ears, Understand with their hearts, And return and be healed.” Then I said, “Lord, how long?” And He answered, “Until cities are devastated and without inhabitant, Houses are without people And the land is utterly desolate, “The Lord has removed men far away, And the forsaken places are many in the midst of the land. “Yet there will be a tenth portion in it, And it will again be subject to burning, Like a terebinth or an oak Whose stump remains when it is felled. The holy seed is its stump.” Isaiah 6:9-13
You will also have to read Matthew 13:13-35
