For some, the imagery of adoption brings up thoughts of being unwanted as we may have had negative experiences with the human adoption experience. But I challenge us to think about adoption in other terms - as being wanted so much that another person goes out of their way to bring a child into their family. Personally I think that adoption is a beautiful action that shows deep love and redemption as a child who had nothing is given a family, a home, love and a new life. It is a life changing event. This is what the Bible tells us happens to us when we put our faith in Jesus. Our lives change!
In 1 John 3:1, John picks up on this theme of being God’s children as he marvels at the present status of believers as God’s children. John speaks of the lavish love of God like a gift that is to be received. The reality of God's love is that he sent his son to die so that we may have new, and eternal, life. Through Christ everything changes - we move from being alienated from God to having the status of his child, from being an outsider who doesn't belong to finding our place in God's family, from being old and tired to being made into a new person who has purpose, from having no hope to having hope.
See what great love the Father has lavished on us, that we should be called children of God! ~ 1 John 3:1a
