fact faces off with emotions

The presence of God is not the same as the sense of the presence of God.  The latter may be due to imagination; the former may be attended with no "sensible consolation."  The act which engenders a child ought to be, and usually is, attended by pleasure.  But it is not the pleasure that produces the child.  Where there is pleasure there may be sterility: where there is no pleasure the act may be fertile.  And in the spiritual marriage of God and the soul it is the same.  It is the actual presence, not the sensation of the presence, of the Holy Ghost which begets Christ in us.  The sense of the presence is a super-added gift for which we give thanks when it comes.
