She will bear a son, and you shall call his name Jesus, for he will save his people from their sins.
"There was no hope for any sinner unless the Son of God Himself should save him. But the apostle Paul, writing to his son Timothy, says, “This is a faithful saying, and worthy of all acceptation, that Christ Jesus came into the world to save sinners;.” (1 Tim. 1:15) You may measure the depth of our danger by the glory of the person of Him who undertook to deliver us from it. It is the Son of God, whom angels worship, who has come “to save sinners.” It must be a deep destruction from which only God Himself could rescue man...
"Jesus Christ did not come into the world to help you to forget your sin. He has not come to furnish you with a cloak with which to cover it. He has not appeared that He may so strengthen your minds (as some men would have you believe,) that you may learn to laugh at your iniquities, and defy the consequences thereof. For no such reason has the Son of God descended from Heaven to earth. He has come, not to lull you into a false peace, not to whisper consolation which would turn out to be delusive in the end, but to give you a real deliverance from sin by putting it away, and so to bring you a true peace in which you may safely rejoice. For, if sin be put away, then peace is lawful; then rest of spirit becomes not only a blessing which we may enjoy, but which we must enjoy, and which, the more we shall enjoy it, the better shall we please our God. 0 sinner, the good tidings that we bring to you, in the Gospel, are not the mere glitter of a hope that will delude you at the last, not a present palliative for the woe you feel, but a real cure for all your ills, a sure and certain deliverance from all the danger that now hangs over you!
