Mystery of Godliness

What we have here expressed to us is this priceless heritage of the Church, "the assembly of the living God"—the "mystery of godliness." It is this knowledge which makes the "house of God" to enjoy, through grace, the revelation by the Father of the Son. We have this in the case of Simon Peter in Matt. 16, "Thou art the Christ, the Son of the living God," or the revelation of Himself to Saul of Tarsus on the way to Damascus: "I am Jesus whom thou persecutest." To the Church of God today is committed the mystery of piety. So we are faced with the fact that the mystery of piety is nothing else than the Lord Jesus Christ Himself, in all the mystery of His divine and, in one sense, unapproachable glory. He is a divine Person, and yet with that intimacy of a Christ made known in humility and love which distinguished Him as a man.
It is having this committed to us, and keeping it enshrined in our hearts above all else, which makes the assembly of the living God "the pillar and ground of the truth." God makes us, aided by His Word and Spirit, to be those who know how to "withstand in the evil day, and having done all, to stand." We must withstand the wiles of the devil, and stand in this blessed truth that God has manifested in the Son. God in all His glory has made Himself known to us in that lowly guise.
