What it means in practical terms to “inherit the Kingdom of God” is not spelled out in Scripture as clearly as how to miss the inheritance is. A basic layer to God’s grace to us is that we can be born of Him by faith, transforming our spiritual lives into having the strength to access abundance and the power to overcome evil. We can overcome the evil in our own hearts and lives, and cooperate with Him to overcome evil in the cultures around us.
Just that basic shift – gaining supernatural life by being born of Yahweh – means that our names are written in His book of life, as described by John in the Revelation of Jesus:
Then I saw a great white throne and One seated on it. Earth and heaven fled from His presence, and no place was found for them. I also saw the dead, the great and the small, standing before the throne, and books were opened. Another book was opened, which is the book of life, and the dead were judged according to their works by what was written in the books.
Then the sea gave up its dead, and Death and Hades gave up their dead; all were judged according to their works. Death and Hades were thrown into the lake of fire. This is the second death, the lake of fire. And anyone not found written in the book of life was thrown into the lake of fire.
(Revelation 20:11-15 Holman Christian Standard Bible®©)
Just not being thrown in the lake of fire means that I don’t experience the “second death.” It doesn’t mean that I have experienced the “life” that is implicit in the presence of my name in the “book of life.”
Experiencing that life happens when I am seeking first His Kingdom and His righteousness. That means living in the place where I find His instructions and His ways. Learning to listen to Him and learning to obey what I hear from Him is the access we have to doing things rightly – walking in righteousness.
Not learning rules – developing a relationship with the Ruler. The two judgments are based on two different criteria: one is identity, the other is works. Everyone experiences both. The works judgment is a Kingdom exam. The identity judgment is a Church exam.
The one that ends in the lake of fire is not based on works. Did you gain an inheritance in the Kingdom? Will you be alive to experience it? Will you be alive, but miss the inheritance by being focused on unimportant things instead? Those are the judgments.
