Regarding Pastor Jerry Dunn's July 26 article, "Don't worry about tomorrow," the early New Testament Christian propagandists preached a non-concern for the future because they were operating under the strong delusion that the Kingdom of God was coming very soon.
Therefore, they reasoned, there was no need to concern oneself with mundane day-to-day concerns.
Then, as time passed, it became evident that the promised Kingdom of God was obviously not arriving. As Dunn points out, 1 Peter 5:7 is an attempt to address this concern by a later generation of Christian propagandists. Dunn's reason for not worrying about tomorrow, that is, to instead "focus on God and His ability to provide for our needs," is radically different from the above reason offered by the early Christians.
I can only assume that Dunn has given up on any hope of a soon-to-arrive Kingdom of God. Oh well, at least in some sense, he is a little closer to reality than were the early Christians.
However, many would question Dunn's assertion that God is displaying much of any "ability to provide for our needs." This assertion has about as much reality content as the related empty formulaic prayer thanking God for our daily bread, uttered with unintended irony by those who have earned their bread by the sweat of their brow.
