The prevailing inability to bear a child yet took its effect on Abraham. God had to open his eyes to see himself as the father of many nations; Gideon never felt he amounted to anything worthwhile until his encounter with God's angel; Mary didn't see any possibility in a virgin having a child without a man until the Holy Spirit overshadowed her. Many of us have had lots of negative experiences that dents our perception of life and questions our ability to do anything differently from the patterns our lives have taken. To all such persons, I change you to see beyond the immediate!
When you look and see with God's eyes, a very magnificent and colourful future unfolds before you. Your destiny holds so much promises to measure and determine its worth using your current reality. Also, it is noteworthy to mention that many great persons we learn about in history arrived their such glorious moments by virtue of the things they suffered. When you look beyond the pain, you would find purpose in it; many great messages have developed out of people's messes! One failure too many shouldn't sentence you to oblivion. Beat a retreat and bounce back to winning ways!
