There are amazing truths - revealed mysteries - given to the faithful in Christ in the Age of Grace.
But one great mystery - the giving of Jesus Christ to and into the formerly pagan believers and their adoption into the family of God is more amazing than all of the others. It shows the power of God in a glorious and manifest manner:
-to break down national differences.
-to break down racial differences.
-to break down barriers of creed and religion and position of birth and wealth.
Jesus Christ alone has done this. He has crushed the barriers that separate man and that have separated man from God.
He gives the power to the sinner to be able to stand again in the presence of the Glory of God.
