I am reading a series of devotional books by F B Meyer (1847 – 1929), one page on each chapter of the Bible. From an entry on Psalm 62:
‘[Abraham] was left waiting till nature was spent… till all that knew him pitied him for clinging to an impossible dream. But as this great silence fell on him, the evidence of utter helplessness and despair, there arose within his soul an ever-accumulating faith in the power of God…
‘This is why God keeps you waiting.’
