As children of God, we have been given the gift of hope. Perhaps you have been waiting for something a long time and discouragement and hopelessness have attempted to settle in you heart. The word of God tells us that when hope is deferred (the Hebrew word, "mashak" meaning, prolonged, seized, or drawn out), it effects our souls, our emotions, our innermost being. As we all know, and medical science supports this, when the "heart"--the seat of our emotions--is sick (weak, diseased, or grieved), it is not long before physical maladies manifest.
If you are in a waiting period of your life, and your hope has been seized, be encouraged. How we handle the waiting period is critical. Trust in God. Believe that all things are working together for good (Romans 8:28). Remember the words of David in Psalm 27:13, "I would have lost heart, unless I had believed that I would see the goodness of the LORD in the land of the living."
