1:18-25 Let us look to the circumstances under which the Son of God entered into this lower world, till we learn to despise the vain honours of this world, when compared with piety and holiness. The mystery of Christ's becoming man is to be adored, not curiously inquired into. It was so ordered that Christ should partake of our nature, yet that he should be pure from the defilement of original sin, which has been communicated to all the race of Adam. Observe, it is the thoughtful, not the unthinking, whom God will guide. God's time to come with instruction to his people, is when they are at a loss. Divine comforts most delight the soul when under the pressure of perplexed thoughts. Joseph is told that Mary should bring forth the Saviour of the world. He was to call his name Jesus, a Saviour. Jesus is the same name with Joshua. And the reason of that name is clear, for those whom Christ saves, he saves from their sins; from the guilt of sin by the merit of his death, and from the power of sin by the Spirit of his grace. In saving them from sin, he saves them from wrath and the curse, and all misery, here and hereafter. Christ came to save his people, not in their sins, but from their sins; and so to redeem them from among men, to himself, who is separate from sinners. Joseph did as the angel of the Lord had bidden him, speedily, without delay, and cheerfully, without dispute. By applying the general rules of the written word, we should in all the steps of our lives, particularly the great turns of them, take direction from God, and we shall find this safe and comfortable.

20. But while he thought on these things—Who would not feel for him after receiving such intelligence, and before receiving any light from above? As he brooded over the matter alone, in the stillness of the night, his domestic prospects darkened and his happiness blasted for life, his mind slowly making itself up to the painful step, yet planning how to do it in the way least offensive—at the last extremity the Lord Himself interposes.

behold, the angel of the Lord appeared to him in a dream, saying, Joseph thou son of David—This style of address was doubtless advisedly chosen to remind him of what all the families of David's line so early coveted, and thus it would prepare him for the marvellous announcement which was to follow.

fear not to take unto thee Mary thy wife, for that which is conceived in her is of the Holy Ghost—Though a dark cloud now overhangs this relationship, it is unsullied still.
