In context Christ is speaking about teaching, true and false prophets. Not about conception.
How could holy God cause someone under the sin of Adam conceive a Holy offspring? You cited the text where the angel explained how He would accomplish that:
Lk 1:35 And the angel answered and said unto her, The Holy Ghost shall come upon thee, and the power of the Highest shall overshadow thee: therefore also that holy thing which shall be born of thee shall be called the Son of God.
Only the fallen in Adam need a savior, Sinless people do not:
46 And Mary said: "My soul magnifies the Lord,
47 And my spirit has rejoiced in God my Savior. (Lk. 1:46-47 NKJ)
If God is not Mary's savior then she lied, a sin.
Not so!
Two ways Jesus is our savior, He forgives our sins: and hecso by His grace preserve us from sin:
Mary was preserved by God from sin!
Gen 3:15 I will put enmities between thee and the woman, and thy seed and her seed: she shall crush thy head, and thou shalt lie in wait for her heel.
(Enmities total war, none of satan’s works found in Her immaculate purity)
Lk 1:28 And the angel came in unto her, and said, Hail, Mary full of Grace, the Lord is with thee: blessed art thou among women.
(Immaculate purity, full of grace, blessed)
Lk 1:35 And the angel answered and said unto her, The Holy Ghost shall come upon thee, and the power of the Highest shall overshadow thee: therefore also that holy thing which shall be born of thee shall be called the Son of God.
(Mary must have immaculate purity)
Lk 1:47 And my spirit hath rejoiced in God my Saviour. (Preserved from all sin in virtue of the merits of the blood of the savior who is Her son)
Lk 1:49 For he that is mighty hath done to me great things; and holy is his name.
(Immaculate conception of Mary and the miraculous conception of Jesus)
Song of Solomon 4:1 Behold, thou art fair, my love; behold, thou art fair; thou hast doves' eyes within thy locks: thy hair is as a flock of goats, that appear from mount Gilead.

Immaculate conception and the Four spiritual laws:
2) Man is sinful and separated from God, so we cannot know Him personally or experience His love.
Man is Sinful.
3) Jesus Christ is God's only provision for man's sin. Through Him alone we can know God personally and experience God's love.
He Died in Our Place.
4) We must individually receive Jesus Christ as Savior and Lord; then we can know God personally and experience His love.
We Must Receive Christ.
Knowing this how can scripture say:
Lk 1:28 And the angel being come in, said unto her: Hail, full of grace, the Lord is with thee: blessed art thou among women.
“Full of grace”
“Lord is with Mary”
(not Mary is with the Lord)
“Blessed”
The only possibility is the “immaculate conception” by the power of God thru the future merits of the passion and death of Jesus Christ! Amen! Lk 1:37 Lk 1:49
