Hosea 14:4

I will heal: it is a usual metaphor in Scripture; sin is our disease. God is the Physician who healeth us, Psalms 103:3 Jeremiah 3:22; and he doth it through Christ, in whom this promise is made to returning backsliders. This promise God maketh by his prophet, to encourage them to hearken to his advice of repenting. Backslidings; aversions, voluntary and wilful turning away from God; well expressed here, and called rebellions by some other interpreters. These voluntary, continued, and obstinate aversions, or backslidings, are instances of greatest sins and sinners; yet God promiseth to heal these old putrefying sores, that we might be assured that he will heal all other lesser wounds: he will fully heal by pardoning and purifying. I will love them; though before he hated, could take no pleasure in them, now he will show that his mind and heart are towards them to accept them, and do them good. Freely; without their desert, and without bounds of time, or measure, or kind. All kinds of mercies the fruit of his love, infinite mercy in grace and glory, eternal mercies, his love will afford to them. This is liberal love indeed, this promised here. For mine anger is turned away from him; I am reconciled to them, my displeasure is turned away.
