Have you ever made a purchase simply because of advertising? One of the most convincing reasons to make a purchase is a “Lifetime Guarantee.” Whenever we see that on a product, we think to ourselves, “Now, that has got to be well made”—so well made, in fact, the company is willing to replace or repair it indefinitely. They stand by their work. We make that purchase with confidence. The author of Hebrews says the same thing in chapter 10. We must trust that the promise is good because the one who made the promise is good. His word is as good as he is.
