In the message of Moses to Israel in Deuteronomy, Moses showed us the danger of unbelief. And he warned that unless we take heed, we will suffer the same awful consequences as those who fell before us: “Lest any man fall after the same example of unbelief” (Hebrews 4:11). He is saying, in essence, “It doesn’t matter what impossibilities you face, or how hopeless things may appear. You are not to fall into the same sin of unbelief. Otherwise, you’ll end up in a terrible wilderness, as they did. And you’ll wander through it for the rest of your life.
“God is faithful to lead you as He led our fathers into their crises for a reason. He wanted to teach them to trust Him. He wanted a people who would be unshakable in their faith. They were to come out of the wilderness with a tried faith that was as pure as gold. He wanted them as a testimony to the world of His goodness toward His people.”
I believe our generation has taken the sin of unbelief too lightly and right now we are seeing the tragic results. I see many believers today who are full of depression and unrest. Of course, some suffer these things for physical reasons, but many others endure such sufferings because of their spiritual condition. In my opinion, their depression is the result of God’s displeasure with their continual unbelief.
The Lord always uses strong language when He refers to unbelief among His people, words such as wrath, anger, abhorrence, tempting Him. Moses made a point to remind the younger Israelites of this: “Thou hast seen how that the Lord thy God bare thee, as a man doth bear his son, in all the way that ye went. . . . And the Lord heard the voice of your words [of unbelief], and was wroth, and sware, saying, Surely there shall not one of these men of this evil generation see that good land, which I sware to give unto your fathers” (Deuteronomy 1:31, 34-35).
