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.
‘This book’ meaning God’s word.. the Truth.. the Bible. If you come to understand and follow His word that should be continuously spoken from us, we will be careful to do/say the right things to be True Ambassadors of Christ. In turn He will elevate us.. reward us for staying faithfully and abiding by it. God is sooo Goood ay.
