The novel shows the hand of God on our lives. This is not always visible at first, but with hindsight we can see God working all things together for good.
Life is not all plain sailing. Rifts can split people apart. Hurt parties wallow, refusing to give up their anger and their hurt. So focused on their past, they risk ruining their future. Our hurts need to be given to God. “The wound isn’t beyond the scope of God’s grace.” We need to receive His healing.
Linked to this theme is that of forgiveness. We need to give out forgiveness before bitterness destroys us.
