There is no where in the bible as such a law of Attraction.
How else would anyone find the right person to marry or have a girlfriend/boyfriend.if they didn't have some sort of lust for each other.
In the bible Matthew 5:27-28 Jesus saying
27 Ye have heard that it was said by them of old time, Thou shalt not commit adultery:
28 But I say unto you, That whosoever looketh on a woman to lust after her hath committed adultery with her already in his heart"
Now if a person noticed ( adultery)
Seeing that Adultery only pertains to those who are married. So these two verse has nothing at all to do with those who are Single.
As for a Single person, whether it be man/woman, to lust after each other nothing wrong in that.
As anyone may haved lust after the other one, to be his/ her girlfriend/boyfriend.
Husband/wife.
Now if a person wishes to follow man's teachings then a single person to lust in having the man/woman as their
girlfriend/boyfriend. husband/ wife.
Then by man's teachings that would be a sin.
But according to God that is no sin, for a single person to lust in having a
woman/ man as their girlfriend/boyfriend
Husband/wife.
How else would anyone get married or have a girlfriend/boyfriend, if they didn't in some way lust after each other.
