Fr. Peter Hocken

Not only will God not reject his promises to his servants, but he will not deny their call and their work.  Just as the Lord always acknowledges the witness of his Old Testament servants, Abraham, Moses and David, so he will always acknowledge the witness of his Christian servants, whether Peter and Paul, Athanasius and Augustine, Francis of Assisi and Thomas Aquinas, Martin Luther and John Calvin, John Wesley and Count von Zinzendorf, Dwight Moody and Charles Spurgeon.
