God had promised a Savior for all mankind. Jesus is the fulfilment of that promise. When He came, His own people were not observant enough to recognize His coming. However, gentile pagans were—even if they did not realize that He was the Savior.
How often are we so entangled in the minutia of our lives, both secular and religious, that we do not recognize the signs that Jesus is entering our lives to save us from all that has us in bondage. We, like the Jewish leaders, may have heard and read the promise; but we do not take the time or expend the effort to look for Him. If we truly believed the promise and the importance to our lives, perhaps we would be more observant.
