Now, dear brethren, whilst all that is unique, and parts Him off from us, do not let us forget that that same sense of Sonship and Fatherhood must be the very deepest thing in us, if we are Christian people after Christ's pattern. We, too, can be sons through Him, and only through Him. I believe with all my heart in what we hear so much about now--'the universal Fatherhood of God.' But I believe that there is also a special relation of Fatherhood and Sonship, which is constituted only, according to Scripture teaching in my apprehension, through faith in Jesus Christ, and the reception of His life as a supernatural life into our souls. God is Father of all men--thank God for it! And that means, that He gives life to all men; that in a very deep and precious sense the life which He gives to every man is not only derived from, but is kindred with, His own; and it means that His love reaches to all men, and that His authority extends over them. But there is an inner sanctuary, there is a better life than the life of nature, and the Fatherhood into which Christ introduces us means, that through faith in Him, and the entrance into our spirits of the Spirit of adoption, we receive a life derived from, and kindred with, the life of the Giver, and that we are bound to Him not only by the cords of love, but to obey the parental authority. Sonship is the deepest thought about the Christian life.
It was an entirely new thought when Jesus spoke to His disciples of their Father in heaven. It was a thrilling novelty when Paul bade servile worshippers realise that they were no longer slaves, but sons, and as such, heirs of God. It was the rapture of pointing to a new star flaming out, as it were, that swelled in John's exclamation: 'Beloved, now are we the sons of God!' For even though in the Old Testament there are a few occasional references to Israel's King or to Israel itself as being 'God's son,' as far as I remember, there is only one reference in all the Old Testament to parental love towards each of us on the part of God, and that is the great saying in the 103rd Psalm: 'Like as a father pitieth his children, so the Lord pitieth them that fear Him.' For the most part the idea connected in the Old Testament with the Fatherhood of God is authority: 'If I be a Father, where is Mine honour?' says the last of the prophets. But when we pass into the New, on the very threshold, here we get the germ, in these words, of the blessed thought that, as His disciples, we, too, may claim sonship to God through Him, and penetrate beyond the awe of Divine Majesty into the love of our Father God. Brethren, notwithstanding all that was unique in the Sonship of Jesus Christ, He welcomes us to a place beside Himself, and if we are the children of God by faith in Him, then are we 'heirs of God, and joint heirs with Christ.'
Now the second thought that I would suggest from these words is--
II. The sweet 'must' of filial duty.
'How is it that ye sought Me?' That means: 'Did you not know where I should be sure to be? What need was there to go up and down Jerusalem looking for Me? You might have known there was only one place where you would find Me. Wist ye not that I _must_ be about My Father's business?' Now, the last words of this question are in the Greek literally, as the margin of the Revised Version tells us, 'in the things of My Father'; and that idiomatic form of speech may either be taken to mean, as the Authorised Version does, 'about My Father's business,' or, with the Revised Version, 'in My Father's house.' The latter seems the rendering most relevant in this connection, where the folly of seeking is emphasised--the certainty of His place is more to the point than that of His occupation. But the locality carried the occupation with it, for why must He be in the Father's house but to be about the Father's business, 'to behold the beauty of the Lord and to inquire in His Temple'?
