Luke 8:21

But since he who does the will of the Father is called sister and brother of the Lord, on account of both sexes who are gathered to the faith, this is not surprising; yet it is greatly to be wondered how one is also called mother. For he deigned to call his faithful disciples brothers, saying: Go, announce to my brothers. Therefore, he who could become a brother of the Lord by coming to faith—it must be asked how he can also be a mother? But we should know that one who is a brother and sister of Christ by believing becomes a mother by preaching. For one gives birth to the Lord, as it were, when one has poured him into the heart of the hearer. And one becomes his mother if through one's voice the love of the Lord is begotten in the mind of one's neighbor. To confirm this matter fittingly for us, blessed Felicity is present, whose birthday we celebrate today, who by believing became a handmaid of Christ, and by preaching was made a mother of Christ. For she feared to leave her seven sons, as is read in the more accurate accounts of her deeds, alive in the flesh after her, just as carnal parents usually fear to send their dead children before them. For when she was seized in the labor of persecution, she strengthened the hearts of her sons by preaching the love of the heavenly fatherland, and she brought forth in spirit those whom she had borne in the flesh, so that by preaching she might bear to God those whom she had borne in the flesh to the world.

He answered and said to them: My mother and my brothers are these who hear the word of God and do it. The whole perfection of heavenly life is comprised in these two things, namely, to hear the word of God and to do it. …

They then who hear the word of God and do it, are called the mother of our Lord, because they daily in their actions or words bring Him forth as it were in their inmost hearts; they also are His brethren where they do the will of His Father, Who is in heaven.

And He therefore knowing their hearts gave them this answer, that meanness of birth harms not, but if a man, though of low birth, hear the word of God, He reckons him as His kinsman. Because however hearing only saves no one, but rather condemns, He adds, and doeth it; for it becomes us both to hear and to do. But by the word of God He means His own teaching, for all the words which He Himself spake were from His Father.

Christ is pleased to own those as his nearest and dearest relations that hear the word of God and do it; they are to him more than his mother and brethren. Christ's Power over the Winds; Christ's Power over the Devils.

And he answered and said unto them,....

These verses form a practical application of the famous parable of the sower. They are intended to nail and clench in our minds — the mighty lessons which that parable contains. They deserve the especial attention of all true-hearted hearers of the Gospel of Christ. We learn, firstly, from these verses — that spiritual knowledge ought to be diligently used. Our Lord tells us that spiritual knowledge is like a lighted candle — utterly useless, when covered with a bushel, or put under a bed.

These verses form a practical application of the famous parable of the sower. They are intended to nail and clench in our minds — the mighty lessons which that parable contains. They deserve the especial attention of all true-hearted hearers of the Gospel of Christ. We learn, firstly, from these verses — that spiritual knowledge ought to be diligently used. Our Lord tells us that spiritual knowledge is like a lighted candle — utterly useless, when covered with a bushel, or put under a bed. It is only useful when set upon a candlestick, and placed where it can be made serviceable to the needs of men. When we hear this lesson, let us first think of OURSELVES. The Gospel which we possess was not given us only to be admired, talked of, and professed — but to be practiced . It was not meant merely to reside in our intellect, and memories, and tongues — but to be seen is our lives . Christianity is a talent committed to our charge, and one which brings with it great responsibility. We are not in darkness like the heathen. A glorious light is put before us. Let us take heed that we use it. While we have the light — let us walk in the light. (John 12:35.) But let us not only think of ourselves — let us also think of OTHERS. There are millions in the world who have no spiritual light at all. They are without God, without Christ, and without hope. (Ephesians 2:12.) Can we do nothing for them? There are thousands around us, in our own land, who are unconverted and dead in sins, seeing nothing and knowing nothing aright. Can we do nothing for them? These are questions to which every true Christian ought to find an answer. We should strive, in every way, to spread our religion. The highest form of selfishness, is that of the man who is content to go to Heaven alone.
