I will be to them a God, and they shall be to Me a people.' Heb. 8:10.
TWO mirrors set over against each other reflect one another and themselves in each other, in long perspective. Two hearts that love, with similar reciprocation of influence, mirror back to each other their own affections. I am thine; thou art mine,' is the very mother-tongue of love, and the source of blessedness. All loving hearts know that. That mutual surrender, and, in surrender, reciprocal possession, is lifted up here into the highest regions. I will be their God, they shall be My people.' That was the fundamental promise of the Mosaic dispensation, laid. at Sinai--Ye shall be unto Me a people for a possession.' All through the Old Testament we find it re-echoed; and yet the interpenetration of God and the people was imperfect and external in that ancient covenant.
So the writer here, falling back upon the marvellous prophecy of Jeremiah, regards this as being one of the characteristics of Christianity, that what was shadowed in Israel's possession of God and God's possession of Israel, is, in substance, blessedly and permanently realised in the relations of God to Christian souls, and of Christian souls to God.
Not only is there this mutual possession, as expressed by the two halves of my text, but each half, when cleft and analysed, reveals the necessity for a similar reciprocity. For God's giving of Himself to us is nothing to us without our taking of God for ours; and, in like manner, our giving of ourselves to God, would be all incomplete, unless in His strange love, He stooped from amidst the praises of Israel to accept the poor gifts that we bring.
So the duality of my text breaks up into a double dualism, and we have God giving Himself to us, and His gift realised in our acceptance of Him for ours; and then we have our giving of ourselves to God, and the gift realised and ratified in His acceptance of us for His. And to these four points, briefly, I wish to turn.
