Miracles do happen everyday and every moment. It is a miracle that we see---it is a miracle that we are able to sleep and recharge our bodies and eat and digest our food. It is a miracle that we hear and breathe and walk. However, the Lord has blessed us so much with these miracles on a daily and moment to moment basis that we no longer realize and acknowledge that indeed we are living miracles. We take for granted His blessings. Our hearts are so disensitized of miraculous awe-inspiring and wonderful gifts from Him that we no longer realize these miracles and thus we relegated them as normal ordinary functions in physical life. So when the supernatural miracles happen, our eyes being so clouded and hearts so heavy with unbelief we do not all the more recognize His supernatural work.
When doctors encounter healings or diseases vanishing without an explanation they stop at saying "there is no explanation," or they say, "it was a misdiagnosis" . If only their hearts look beyond what is physical and think of God who creates and heals and orchestrates things, then they will discover HIs greatness and lovingkindness. If only they shed their unbelief and look through the eyes of faith, they will find out that there is nothing impossible with God, and He does as He pleases and when He does, He does it well.
