Our church has been reading through the book of Joshua the last few weeks. I read Be Strong (Joshua): Putting God’s Power to Work in Your Life by Warren W. Wiersbe along with our daily Bible reading.

Joshua marks two major transitions in Israel’s history. First, Moses, their leader of over forty years, had just passed away. Then the Israelites had just finished forty years of wandering and were about to enter the land God had promised their ancestors long ago.

Either situation would be daunting to a new leader. So God encourages Joshua right off the bat:

No man shall be able to stand before you all the days of your life. Just as I was with Moses, so I will be with you. I will not leave you or forsake you. Be strong and courageous, for you shall cause this people to inherit the land that I swore to their fathers to give them (Joshua 1:5-6).

God also gives Joshua vital instruction:

Only be strong and very courageous, being careful to do according to all the law that Moses my servant commanded you. Do not turn from it to the right hand or to the left, that you may have good success wherever you go. This Book of the Law shall not depart from your mouth, but you shall meditate on it day and night, so that you may be careful to do according to all that is written in it. For then you will make your way prosperous, and then you will have good success. Have I not commanded you? Be strong and courageous. Do not be frightened, and do not be dismayed, for the Lord your God is with you wherever you go (Joshua 1:7-9).

Joshua seems to have followed God’s instruction faithfully throughout the rest of his life. He made a couple of costly mistakes: going up to Ai and making a pact with the Gibeonites without seeking counsel of the Lord. But Wiersbe spends a lot of time pointing out that when we err, we don’t give up: we confess our sins, pick up again, and get back on the right path.

Wiersbe discusses the difficulty of God having His people slaughter the nations in Canaan. He points out that the Canaanites weren’t innocent: they were known for cruel acts like sacrificing their children to their gods and vile sexual acts in the name of worship. And he reminds that God gave them plenty of space to repent. Rahab was one who heard of the God of Israel and turned to Him in faith (eventually becoming an ancestor of the Messiah).

Some hymns have portrayed the promised land as symbolic of heaven. But Wiersbe repeatably points out that the symbolism doesn’t fit: we don’t battle our way either into heaven or after we get there. He says that entering the promised land symbolizes our maturity in Christ. God often said that He was the one driving out the nations before Israel, yet they had to pick up their swords and fight (most of the time. Jericho and some of the other cities had different battle plans). So with us: we’re saved by grace through faith plus nothing. And we’re sanctified by grace as well. Yet we only become mature Christians as we pick up our “sword of the Spirit,” God’s Word, and believe it and apply it. We can and should pray for God’s grace and help in taking temptation away and helping us overcome, but He expects us to read and apply the Word He gave us. “What Paul’s letter to the Ephesians explains doctrinally, the book of Joshua illustrates practically. It shows us how to claim our riches in Christ. But it also shows us how to claim our rest in Christ (p. 22, Kindle version). Wiersbe discusses briefly the different kinds of rest Hebrews 4 and 5 tell about, then says, “This ‘Canaan rest’ is a picture of the rest that Christian believers experience when they yield their all to Christ and claim their inheritance by faith” (p. 22).

The victorious Christian life isn’t a once-for-all triumph that ends all our problems. As pictured by Israel in the book of Joshua, the victorious Christian life is a series of conflicts and victories as we defeat one enemy after another and claim more of our inheritance to the glory of God (p. 23).

The main point of Joshua is that God kept His promises to His people. Not only did He give them the land He originally promised Abraham, but He provided for each of the tribes. At the end of the book, Joshua tells the people, “You know in your hearts and souls, all of you, that not one word has failed of all the good things that the Lord your God promised concerning you. All have come to pass for you; not one of them has failed” (Joshua 23:14). He encourages them to “cling to the Lord your God just as you have done to this day” (23:8) and warns that just as God kept His promises to give them the land, He’ll keep His promise to punish them if they go after other gods.

Wiersbe has a closing chapter of the example of Joshua himself in his following the Lord and leading the people.

As always, I appreciate Dr. Wiersbe’s insights into this book of the Bible.
