If they had a social gospel in the days of the prodigal son, somebody would have given him a bed and a sandwich and he never would have gone home.
There is a trend today that would put a new robe on the prodigal son while he is still feeding hogs. Some would put the ring on his finger while he still in the pigsty. Others would paint the pigsty and advocate bigger and better hog pens.
Christmas is based on an exchange of gifts, the gift of God to man - His unspeakable gift of His Son, and the gift of man to God - when we present our bodies a living sacrifice.
If I had only one sermon to preach it would be on the Lordship of Christ. When we get right on that point we are right all down the line. God honors the exaltation of His Son.
