When you establish a relationship with the Holy Spirit, you will turn to the Word of God first and foremost. Let your first defense be the Word of God when an issue arises or when the enemy tries to attack. Remember not to rely on your own understanding, but to fully trust in and rely on the Word of God.

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. Joshua 1:8 (KJV)
