The renewal of the mind comes with the meditation and imbibing of God’s Word in our heart and life. Moses left a deep conviction in Joshua’s heart of the benefit of keeping God’s Word. As Joshua inherited the mantle from Moses, the LORD gave him these instructions in Joshua 1:8, “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 lived a fruitful life in obedience to God’s Word.
