Beware of those who mind earthly things
Israel walked under the physical letter of the law. Their faith was connected to signs and miracles which showcased the power of God in this earthly environment. Their inheritance is the earth, the physical realm, the tangible things.
Today, however, in this dispensation of grace, we are called to walk according to a different realm. We walk according to the newness of the spirit (grace), not the oldness of the letter, (law). (Rom.7.6). Our dispensation is not connected to the natural world. Our faith is not connected to signs and miracles, or to anything tangible. Paul writes that our walk is from faith to faith (Rom.1:17), from our initial faith in the gospel to our continued faith in the knowledge of the Word, applied to our daily walk. Our inheritance is the heavens, the spiritual realm, the things that are not of this world.
Now, why do I mention all this?
