Have you ever been called by the Lord to do something really hard? Forgiving someone who doesn't deserve it is one of the hard tasks the Lord calls us to do. Have you ever been convicted by the Word and the Spirit that you really needed to forgive someone, but you just didn't want to do it? Maybe the person had sinned against you too many times or in a seriously damaging way. Whatever the reason, you knew you needed to forgive them, but you just weren't sure how.
Hosea was called by the Lord to do something most of us would consider nearly impossible.
