It is human nature to want to use whatever means available to us to succeed. However, a conflict arises when we place our total trust in ourselves instead of God. The idea of maintaining a proper balance between trust and obedience to God versus placing an over dependence upon our natural skill and resources has created problems since Genesis. We are prone to build strong defenses through our natural gifts to avoid failure and use all of our might to be successful in our endeavors. However, this can often be done at the expense of the supernatural in our lives. When it comes to receiving from God, it is important we don't make the same mistake Moses made when God told him to speak to the rock in order to receive water for the people. Instead, He struck the rock and failed to enter the Promised Land. The people of Israel often fell back to trusting in their own abilities and God had to send a reproof into their lives.
How do we avoid the trap and maintain a proper balance between the natural and the spiritual? The rule of thumb is to submit every activity to God and use your skill as God directs you. Be sensitive to God's leading in all your activities. Avoid trying to build resources for the sake of insulating yourself against calamity which is rooted in fear.
Finally, follow Solomon's advice: "Trust in the LORD with all your heart and lean not on your own understanding; in all your ways acknowledge him, and he will make your paths straight" (Prov 3:5-6).
