All whom The Lord Jesus Christ saves, they have been ordained unto good works Eph 2:8-10
8 For by grace are ye saved through faith; and that not of yourselves: it is the gift of God:
9 Not of works, lest any man should boast.
10 For we are his workmanship, created in Christ Jesus unto good works, which God hath before ordained that we should walk in them.
And that which she was performing upon Christ her Lord and Saviour was a good work Matt 26:9-11
9 For this ointment might have been sold for much, and given to the poor.
10 When Jesus understood it, he said unto them, Why trouble ye the woman? for she hath wrought a good work upon me.
11 For ye have the poor always with you; but me ye have not always.
3 And being in Bethany in the house of Simon the leper, as he sat at meat, there came a woman having an alabaster box of ointment of spikenard very precious; and she brake the box, and poured it on his head.
4 And there were some that had indignation within themselves, and said, Why was this waste of the ointment made?
5 For it might have been sold for more than three hundred pence, and have been given to the poor. And they murmured against her.
6 And Jesus said, Let her alone; why trouble ye her? she hath wrought a good work on me.
7 For ye have the poor with you always, and whensoever ye will ye may do them good: but me ye have not always.
8 She hath done what she could: she is come aforehand to anoint my body to the burying.
9 Verily I say unto you, Wheresoever this gospel shall be preached throughout the whole world, this also that she hath done shall be spoken of for a memorial of her.
Now couple that with the fact that she is said to Loveth much because she perceived she was forgiven much as stated here Lk 7:47
Wherefore I say unto thee, Her sins, which are many, are forgiven; for she loved much: but to whom little is forgiven, the same loveth little.
This was her Faith working by Love Gal 5:6
For in Jesus Christ neither circumcision availeth any thing, nor uncircumcision; but faith which worketh by love.
Faith in Christ will always be accompanied by Love, because they both fruit of the Spirit of Christ in them Gal 5:22 and because they both Gifts of His Grace , Paul writes 1 Tim 1:14
And the grace of our Lord was exceeding abundant with faith and love which is in Christ Jesus.
Thats because they are fruit of His Spirit which He gives to each redeemed sinner whom He dies for; Also because they are in Him. Yes the women was in Christ Jesus. Faith and Love they come from the Bridegroom, who is the Head of His Body the Church, His Bride.
Faith in Christ must be accompanied by Love or it is nothing 1 Cor 13:1-2
Though I speak with the tongues of men and of angels, and have not charity, I am become as sounding brass, or a tinkling cymbal.
2 And though I have the gift of prophecy, and understand all mysteries, and all knowledge; and though I have all faith, so that I could remove mountains, and have not charity, I am nothing.
That word charity is the greek word ἀγάπη and is translated Love up to 86 times ! Its the word used here Lk 7:47 !
Now this is crucial to understand and also shows the absurdity of how a unregenerate sinner can have Faith in Christ, when that Faith works by Love, and it is above blasphemy to suggest that a unregenerate sinner can Love the Lord Jesus Christ, but yet that is exactly what the enemies of God are telling us when they tell us that one can believe on Christ in Gospel Obedience in a unregenerate state, you may as well say also that a unregenerate sinner can Love God as well, void of God's Spirit !827
