For by grace are ye saved through faith; and that not of yourselves: it is the gift of God. – Ephesians 2:8

“Thy faith hath saved thee.” – Luke 7:50

Jesus is so fond of faith that He takes the crown from His own head, and puts it on the head of faith, as He says to the woman, “Thy faith hath saved thee.” Is that a safe thing for Christ to do? Oh, yes! because faith at once removes the crown from her own head, and puts it back upon Christ’s, saying, “Not unto me, not unto me, but unto Thy name be all the glory.” Christ loves to crown faith because faith loves to crown Christ. As for boasting, faith cannot tolerate that for a moment; she hurls it out of the window, and will have nothing further to do with it. Our Saviour speaks thus, “Thy faith hath saved thee,” because He knows that it will be understood that faith is only the connecting link with Himself, that He really works the salvation, but that the faith of the believer is the means of obtaining it.

This woman’s faith was a personal faith. O dear friends, I implore you to give up all idea, of being saved by anybody else’s faith! Thou must believe in Jesus for thyself, or thou wilt be a lost man for ever. What a dreadful falsehood it is when men stand up, as sponsors for a child, and promise and vow various things, none of which are within their power to perform! Notice, next, that this woman’s faith was a practical faith. She was saved by faith, and not by works; but, she was not saved by a faith which did not produce works. Think of her works,-she washes the Master’s feet with her tears, and wipes them with the hairs of her head; she kisses them repeatedly, and anoints them with her precious ointment. I may truly say of her, “She hath done what she could.” The faith which saves is not a barren faith; it produces the good fruit of love and service for Christ, ~ C.H. Spurgeon
