In other words, the Lord loves us as a groom loves a bride, -- and most grooms get jealous if their bride is spending more time with another man.
Exodus 34:14 "The Lord, whose name is Jealous, is a jealous God."
The dilemma is this: love, by its very nature, must be voluntary, freely given. The moment it is forced, it is no longer love - it evaporates.
William Penn experienced imprisonment in the Tower of London. He wrote in England's Present Interest Considered, 1675:
"Force makes hypocrites, 'tis persuasion only that makes converts."
God wants our love, but He refuses to force it, for if He did, our response would no longer be love. It might be submission, or obedience, or fear, but it would not be love freely given.
