Deeply embedded in almost every part of the Bible is a tension between the holiness of God and his graciousness.
As a holy God he demands compliance with his law, set before human beings choices of obedience or disobedience on which are conditioned blessing or judgment.
As a merciful, gracious, and compassionate God, he makes unconditional promises reflecting the grace and favor he has set on his people.
Joshua 1:1-8 expresses no less than ten “will”s, of which the Lord is personally speaking to a stalwart of a man, of which every one of them were fulfilled.
What was true for Joshua is certainly true for each of us- “Do not let this Book of the Law (probably Deuteronomy) depart from your mouth; meditate (hagah) on it day and night, so that you may be careful to do everything written in it. Then you will be prosperous and successful” (Josh1:8).
Then to close the book, Joshua sums up everything ever learned from Moses and challenges the people, “Now fear the Lord and serve him with all faithfulness. Throw away the gods your forefathers worshiped beyond the River and in Egypt, and serve the Lord. But if serving the Lord seems undesirable to, then choose for yourselves this day whom you will serve, whether the gods your forefathers served beyond the River, or the Gods of the Amorites, in whose land you are living. But as for me and my household, we will serve the Lord” (Josh 24:14-15).
Each of us is going to worship and serve something. What or who is it going to be for you?
