We wrestle with God when we:
Waste our time complaining. Instead of resting in the position of being appreciative for what God is doing for us as we trust Him to do the leading in our life to prevent unnecesary wondering in life's deserts.
Refuse to listen to what God has to say. Instead of resting in the comfort of God’s wisdom and words that He has for us to hear.
Expect things to go according to our will. Instead of resting in knowing that God knows what He’s doing and whether we want to accept it or not, His will is the best way to go.
Stagger away from obedience in Christ. Instead of resting in the knowledge that God’s rules have a purpose, set up for our spiritual guidance and growth.
Test God. Instead of taking the tests He has for us resting on the fact that He will help us study and see us through each one.
L ook towards other things rather than God. Instead of resting on the reliance we have in the Lord to see us through life one day at a time.
Extinguish the light of the Lord. Instead of adding to the restful light He already supplies, lighting the way for those living in the dark to find Jesus.
Closing thought: Often we ask ourselves the very question we read in Psalm 13:2, "How long must I wrestle with my thoughts,' as we add, 'How long must I wrestle with God?"
Only we can answer that, it's not God wrestling with us, it's us wrestling with God. As we read in Ephesians 6:12 our struggle or wrestling "is not against flesh and blood but against the rulers, against the authorities, against the powers of this dark world and against the spiritual forces of evil in the heavenly realms." That's what we are up against and its up to us to stop and realize it and fight not against God but for God if we ever hope to win.
