Spend time in God's Word (see Joshua 1:. It may be dry at first.
His Word is light, life, health and strength. If you don't put the Word into your spirit, you will not be able to reach your high calling and do what is right.

Psalm 119:11 says, "They word have I hid in mine heart that I might not sin against thee." If there is no Word in your heart, you are going to sin against God.
You see, when you are under stress and spiritual attack, what is in you is going to come out. If you have not put the Word in you, when pressure comes, whatever is in you will manifest.
If you put the Word in your spirit, it cleanses you, regenerates you, renews you, strengthens you and builds you so that when pressure hits, instead of goop coming out, the Word come out. The principles of God come out. The strength of God comes out of your spirit.

Listen to what God told Abraham in Genesis 17:1
. . . I am the almight God; walk before me, and be thou perfect.
