So to acknowledge God means also to seek God s will and wisdom for your situation recognizing that He is your boss and your guide and once finding what God wants you doing, you go do it. You see the Jewish mind almost always connected action to mental belief. You could not say you believed something unless it showed in your actions. People would know you weren t telling the truth if your actions did not confirm what you said you believed. He was saying the works proved what you said about your faith.
Talk is cheap, actions are proof.
Any area in your life where you are not responding in action according to what you are telling people you believe regarding the Christian life is an area in which you have not acknowledged God. Remember, when we acknowledge God, we are accepting His right of rulership over us, His right to tell us what to do, and it is our responsibility to do it. In order to acknowledge God, you have to obey verse 5 first. And note the last half of verse 5. Lean not on your own understanding.
