love is a strong connection between two individuals that can have a sexual connotation but is not limited to one. love is the tie that binds friends family and communities.
lust is a completely biologically-based sexual feeling that serves to fulfill reproductive urges.
the big difference between the two is that love is an emotion and lust is an urge. while the two are often experienced together, both can be felt separately without any hint of the other.
for example: you see a person on the street that catches your eye and you immediately fantasize about having sex with them. just because you are attracted to them and are smitten with lust does not neccessarily mean that you care about their well being and have a strong emotional bond with them.
the converse is also true. you have strong feelings of love for you family (most people do anyway) but you do not want to have sex with them. this is also true of close friends. we all have had a friend or two that we could never picture having sex with. (this is especially true in hetero friendships with the same sex and gay male/ straight female friendships, or vice versa).
so yeah, id say that there is a big difference between the two. but thats just my opinion. feel free to counterpoint.
