"As the bridegroom rejoices over the bride, so shall your God rejoice over you."

The reality is most do not believe in the intensity, purity and singleness of devotion with which God loves them.  They believe they are too unworthy, too impure, defiled, unholy.  Perhaps nothing in their upbringing showed them that they were worthy of such lavish attention, especially by God whom so many easily understand as judge but not lover.

The God who reveals himself to us is nothing like the god of our misconceptions.  When the God of revelation desires to reveal the intensity and singleness of his love for us he turns to the most unconditional of human love to help us understand: the parental love of a mother for her child, the marital love of a bridegroom for his bride.  How would the mother feel if her child did not believe in her love but went wandering off in search of affection?  How would the bridegroom feel if the bride suddenly became self-aware and felt unworthy and incapable of accepting his love?  This is why only the childlike can enter the Kingdom of Love.  They have the self-forgetfulness and simplicity to believe totally in God's unconditional, parental, marital love for them.  The saints believed in that love.  That belief was their impetus for sanctity.  Indeed that belief sanctified them.  "Sanctify them in the truth; your word is truth." (John 17.17)
