Another reason perfect love is difficult to comprehend is that it has no end. Since there is no human basis for its beginning, there’s nothing we can do to end it. God’s perfect love is eternal love. It can’t be earned by what you do nor forfeited by what you don’t do. You can choose to receive it, or you can choose to ignore it, but you can’t end it. God will not force you to enjoy his love, but you can’t stop him from offering it.
