"Whereby are given unto us exceeding great and precious promises: that by these ye might be partakers of the divine nature" (2 Peter 1:4)
It is the teaching of Meister Eckhart that thee is something far inside the mysterious depths of a human life which is unknown except as God and the individual know it. This he called the "ground" of the soul.
This "ground" is, according to Eckhart, the stuff which once received the image of God at creation. The lesser powers of the soul are the instruments through which this mysterious primal stuff makes itself felt in the world. These powers are imagination, reason, the faculty of speech and the creative powers.
In this far-in sanctuary, God reveals Himself to the individual as a "birth", bringing forth a new creation by the regenerating act of the Holy Spirit. Thus we receive from Christ the very nature of God (2 Peter 1:4) and are spiritually prepared for the full revelation of Christ in us, the hope of glory.
In that blessed moment of appropriating faith [Christ] gives Himself to us as our complete life, covering all our future need, and day by day we just enter into it step by step.
