I think that there are a lot of people in our society that feel like they are fatherless/motherless. There is the fact that many families today are one parent families but also there are fathers and mothers that are absent in some way but present in other ways. If our parents are like this we can be left with an inability to relate to God as a good solid parent and receive the benefits of his parenting.
So this song is not just for the physical orphan. This song has been knocking about in my head for weeks and weeks and I have to say that God is using it to convince me of his unconditional unwavering love for me and not just that but his approval too.
