As with all blessings from God, Satan often twists their purpose and uses them to distract us from our relationship with the Giver of all good gifts.  Instead of trusting in the promises that God gives us in His Word, we often put our trust in our own abilities and possessions.  We risk hardening our hearts and being led away from God instead of being strengthened and steadfast in the one true faith.  As God's people, we receive many and varied material things in this life, but the greater blessing is what awaits us in the life of faith, eternal life.
