In our text, we are given two great promises. First, we see a promise to the upright - He (God) stores up sound wisdom for the upright. We can never draw down or deplete this storehouse. God has wisdom to give, and He gives liberally (James 1:5). Solomon emphasizes "sound" wisdom. This refers to the nature of the wisdom that God provides. Sound wisdom will always cause you to honor God and lead you to emulate Christ. Sound wisdom is in contrast to worldly wisdom and counsel that would lead you away from serving Christ. This wisdom is reserved for those who desire to walk upright (those who deal honestly with God and man). Sound wisdom is not reserved for the dishonest or deceitful. It is a contradiction in terms to desire godly wisdom, but speak with the tongue of the evil one and act in deceptive/destructive ways.
Second, God gives a promise to be a shield to those who walk in integrity. This is important for us as Christians to grasp. We live in an age that promotes dishonesty. When tempted to go the way of the world and deal dishonestly, we should remember this promise. God is a shield to those who walk in integrity. To deal deceitfully in either word or action, brings us out from under the protection of God.
May God cause our hearts to desire to walk uprightly and claim these precious promises
