Therefore since it still remains for some to enter that rest, and since those who formerly had the good news proclaimed to them did not go in because of their disobedience, God again set a certain day, calling it Today. This he did when a long time later he spoke through David, as in the passage already quoted: Today, if you hear his voice, do not harden your hearts. (Hebrews 4:6-7)
A few years back, Jack Bauer had a very long day, the first of several that provided the material for the program 24. In the Jack Bauer universe, nothing matters but today. In fact, Jack doesn’t even think about the entire day. He thinks about particular slices of that day. In the span of a morning, he attacks a superior officer, gets into a gunfight rescuing a colleague, abducts another colleague, foils an assassination attempt, and much, much more.
My life does not revolve around ‘yesterday.’ Yesterday I wasted some money, procrastinated on some needed work, and hollered at my dog. Similarly, my life does not focus on “tomorrow.” Tomorrow I might find $187,000 and I might have a heart attack. I can’t change yesterday and I can’t control tomorrow. All I can do is respond with bold obedience to “Today.”
That’s what I get from all this focus on “Today” in this passage.
