Obedience is the practical acceptance of the authority and will of God. It includes both submitting to Him and then expressing that submission in actions, words and thoughts. To be obedient is to be in agreement with God. To be in agreement with God is to be in a position of power in Christ.
Disobedience is caused by rebellion and distrust of God. To be disobedient is to yield to self-will instead of surrendering to God and desiring His will in all things.
“‘Teacher, which is the greatest commandment in the Law?’ Jesus replied: ‘Love the Lord your God with all your heart and with all your soul and with your entire mind.’ This is the first and greatest commandment.'”
