Blackaby notes (Experiencing God, Page 157):
In many ways, obedience is your moment of truth. What you do will:
1. Reveal what you believe about God.
a. Do you believe God does what He says He will do!
2. Determine whether you will experience His mighty work in you and through you.
3. Determine whether you will come to know Him more intimately.
4. (I add) Your willingness to obey God will determine whether you have a strong love relationship with Him or not.
