There is much to be joyful about! Hear that and beleive it! If it were not so, why would the sick cling so desperatly to life? When we focus on God and his love for us, we are released to express our joy, but without some sorrow in life, we would have no capacity to appreciate that which brings us joy. Kahlil Gibran expressed this concept beautifully in his book, The Prophet, saying "The deeper that sorrow carves into your being, the more joy you can contain."
Rich or poor, weak or strong, powerful or oppressed...the Lord has given us all the same opportunity to seek Him in wisdom. We all have the capacity for sight. Even those who may not have the gift of sight in the physical body, still are capable of spiritual vision. We need to see this world as the Lord sees it, to fulfill the task he has set before us.
We have all heard the phrase "life is not fair" and have felt at some point that God must not really care about us. It is at these times when we must stop looking for fulfillment to come from the world, but rather from He who is our true Provider. There are times in life when we grow by leaps and bounds, and other times when pruning is necessary. In times of deepest darkness He is still there for us. He is our hope and our strength, and if we allow Him to guide us through the darkness, we will discover in the light of day that even those dark times were ultimately for our benefit.
