He was saying that when our minds are renewed, we will see the Kingdom displayed and proven as He did in His earthly ministry. That's what it means to "see" the Kingdom of Heaven. Our souls long to see such things. We have inside of us an unrelenting hunger to watch the Kingdom break into this realm-and not just to watch but to participate, to become the connecting point and gateway for God's power.
The author emphasizes that the renewal of our minds is essential for experiencing and understanding the Kingdom of Heaven, akin to how it was manifested during Jesus' earthly ministry. This process of renewal allows us to truly perceive the divine reality around us, fulfilling a deep desire within our souls to witness the Kingdom's influence and presence in our lives.
Moreover, there is an inherent yearning in everyone to not only observe the Kingdom's workings but also to actively engage and be a conduit for God's power in the world. This call to action invites individuals to embrace their role as gateways through which the transformative power of the Kingdom can enter our reality, connecting believers to God's greater purpose.
