There is a sense in which we are all sons and daughters of God, for we are not only made by him, but also made in his image and likeness. This is suggested by Luke’s genealogy and it is good and right to affirm this. However because we are made in God’s image and likeness, we are also made for a deeper, richer sonship (and daughter-ship!) that cannot be a simple fact of nature, nor can it be obtained by our own efforts. It must be obtained through the unmerited gift of grace, by uniting ourselves to Christ and being baptized in to his uncompromising obedience to God manifested in his life, death and resurrection.
