Joshua 1: 8-9
"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. Have I not commanded you? Be strong and of good courage; do not be afraid, nor be dismayed, for the Lord your God is with you wherever you go."
We have been commanded to read and meditate on God's word throughout the day. When we are at work or in an environment where we are unable to physically look at scriptures, we can speak them in our minds. The more time we spend in the word, the more our hearts will be focused on the things of God. Reading the bible builds up our faith and makes us strong even when we feel weak.
