Nicodemus answered him, "How can these things be?"
Some of the questions which are similar to the one that Nicodemus raised here are: (1) How did God create the heavens and the earth?  People strive in vain to answer this; but they cannot agree.  It is enough for the child of faith to believe that "God spake, and it was done; He commanded and it stood fast"  (Psalms 33:9).  (2) How does God answer prayer?  Does He answer by performing a miracle?  How can prayer do any good when God already knows everything?  We must confess a little sadly that we do not know; but we believe that "The effectual fervent prayer of a righteous man availeth much" (James 5:16).  (3) How are the dead raised up?   (1 Corinthians 15:35).  This is another "how" that torments the intellect endlessly; but the believer holds that it is no more difficult for God to give one another life than it was for Him to have given him the first life.  The soul's deepest instinct demands belief in a resurrection; but "how" it will come to pass is a problem beyond the perimeter of man's ability to solve problems.  And yet there is an instinct supporting the divine revelation that a resurrection will indeed occur.
