You must know the Word of God so you can do the Word of God and prosper because of the Word of God.
Read: Joshua 1:8
This Book of the Law shall not depart from your mouth, but you shall read [and meditate on] it day and night, so that you may be careful to do [everything] in accordance with all that is written in it; for then you will make your way prosperous, and then you will be successful.
