This Book of the Law shall not depart out of thy mouth; but thou shalt meditate therein day and night, that thou mayest observe to do according to all that is written therein; for then thou shalt make thy way prosperous, and then thou shalt have good success, Joshua 1:8.

Moses, Joshuas mentor, had died; but Gods book was still available to Joshua.

Gods book of the law contained His word and His promise for a prosperous way and good success. Now there were three things that Joshua had to do for God to fulfill His promise.

One, Joshua was to know what was written in the book. In plain words, he was to read the book.

Two, Joshua was to meditate upon the words of the book day and night. In doing that he would know what God expected of him in how he should order his life and what he should do.

Three, Joshua was to make a personal application of all that was written in the book. He did not have the liberty to pick and choose what he liked and to reject the parts that may have been distasteful to him.

From our text, we too can learn that by reading, meditating, and applying Gods word, the same God of Joshua will also fulfill His promise to us of a prosperous way and good success.
