Brandon, I thought you knew everything!
Seriously, Bro, Don't tell me that your spirit does not understand that "take no thought" when taken in context with the whole chapter means that we are not to be controlled by the worries of this world. I have lived my entire adult life serving Christ as my master, trusting in Him to supply my needs as He sees fit. I have claimed this chapter and have preached it for 30+ years. My life is evidence that God provides. "All these things" have been added to me and my family since my ministry began! Now I am told that this command and its related promise are not mine to claim?! Yes, I work. That is part of God's providence! I have done everything from flip burgers to land clearing. I have been in the computer industry from the time the the TRS-80 (Model 1!) was the PC. I now am a bookkeeper after I leave the church every day. In all this, I have never been without, and I have never feared that I would be without, because of Matthew 6. My kids never missed a meal. The 2 out of the 4 that wanted to attend college finished with no debt. DON'T TELL ME that only the Jews can claim this promise. AIN'T HAPPENIN'!!
I think that "D"ispensationalists have completely misunderstood what "d"ispensation is really all about. Hint: What is the root word for dispensation? - Dispense ... to disperse or to pass out. The "dispensation of grace" referred by Paul is the special grace given TO HIM to be the one responsible to carry out his ministry as the apostle to the Gentiles. It is not the signal of a new era within the timeline of God's plan.
