Ephesians 3:10 so that through the church the manifold wisdom of God might now be made known to the rulers and authorities in the heavenly places.
So through the Church, that is the body of Christ, God choses to display His manifold wisdom. In time passed He chose certain people and prophets to speak to His people Israel. And other times by direct communication. But the all encompassing mystery , the grafting of the gentiles, the appointed apostles, being the foundation of the church with Christ as the corner-stone. The Gospel, which is the pure product of the wisdom of God; which is gloriously displayed in the several doctrines of it; as in election, in choosing men in Christ and for the security of His Promise in founding it not upon their works, but his own grace. In redemption, which is seen in the person of the Redeemer, who is both God and man. And in the manner in which it is displayed, being both for the glory of God’s grace and mercy, and for the honour of his justice and holiness. And wherein Satan is mortified, sin is condemned, and the sinner saved. And in justification, whereby sinful men become just with God: God is just, and yet the justifier of them that believes. And the ungodly is justified, not justified in his ungodliness, but from it: and is pardon of sin. To receive pardon from sin is to say it never happened. And it may be called “manifold”, because of its various doctrines and promises and because of the wisdom in them, and the various persons to whom it is made known, and the various times in which it is displayed. So now under the Gospel this is more clearly known, or made known to the angels by the church of God, through the ministry of the word in it, on which angels attend, being desirous to look more diligently into the mysteries of it; and by the displays of the wisdom and grace of God unto his church and people.
