Optimists do not ignore the difficulties; they are keenly aware of them. But the knowledge of God's presence prevents them from being discouraged or giving up. It is impossible to stand in the presence of God and be a pessimist! The account of David and Goliath vividly pictures the source of the Christian's strength -- not our own size, strength, or resources, but the power of almighty God. If we focus on our opposition and problems, they will seem gigantic. But as we focus on God, we will see our situation in the proper perspective and be assured that all things are possible with God (Phil. 4:13)." - Henry Blackaby
