How Have We Missed This?

How have we missed this? Jesus very clearly calls us to a new Kingdom. In that call, we are called out of the old kingdom (The world). In the old we found very few answers to meaningful questions. In the new, we find all wisdom and all power and fullness of life.
That begs the question, why are we messing around with the old kingdom when we have so much offered in the new one. We are a hardheaded and slow species sometimes without a doubt.
I hope that your meditations and devotions lead you further into the new Kingdom and that this year will end with you making a life-changing discovery if you have not already. “But seek first His Kingdom and His righteousness, and all these things will be given to you as well.”- Matthew 6:33
