“God made known to us the mystery of his will according to his good pleasure, which he purposed in Christ as a plan for the fullness of time, to unite all things in him, things in heaven and things on earth” (Ephesians 1:9,10).
When God’s time had fully come, the mystery, which God purposed in Christ came into the world in the man Jesus. Through him all things were created. In him all things are restored to the purpose of the divine will. He is, therefore, the mystery, God’s eternal purpose, moving into time as the beloved one. He is in himself the union between God and man in whom we and all things become one.
Now, by the Spirit, we take part in the mystery for the Spirit brings us into living union with the one who is the mystery. By the Spirit, we are in Christ sharing all he has with his Father in deep union and communion. By the Spirit, Christ is in us living out his own life with the Father through us. This is the mystery that was hidden from the beginning and now an open secret among us in union with Christ. The mystery that moves towards fulfilment and consummation among us as Christ’s body, ‘the fullness of him who fills all in all’ (Ephesians. 1:23). Until that day dawns we enjoy fellowship in the mystery, for it is the mystery of God’s will, which he purposed in Christ and we are part of it all by his Spirit.
