Joshua chapter 1:8. Today's version

 Joshua 1:8
This Book of the Law shall not depart from your mouth, but you shall meditate in it day and night, that you may observe 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.(NKJV)

The Bible is your guide. You are not just to read it, you are to also profess it, confess it and declare it to others. Everything you are expected to do is already contained therein. Follow it to the letter, that is the only assurance you have that you will be successful in all you do and that you will be abundant and plenteous in all riches. (Today's Version)
