John Owen, Communion With God, ch.3

The love of God is like himself – equal, constant, not capable of augmentation or diminution; our love is like ourselves – unequal, increasing, waning, growing, declining. His, like the sun, always the same in its light, though a cloud may sometimes interpose; ours, as the moon, has its enlargements and straitenings.

The love of the Father is equal; whom he loves, he loves to the end, and he loves them always alike. “The Strength of Israel is not a man, that he should repent.” On whom he fixes his love, it is immutable; it does not grow to eternity, it is not diminished at any time. It is an eternal love, that had no beginning, that shall have no ending; that cannot be heightened by any act of ours, that cannot be lessened by anything in us.
