Genesis 3:15 From now on, you and the woman will be enemies, and your offspring and her offspring will be enemies. He will crush your head, and you will strike his heel. 

The Scriptures do state that it points to Jesus. I believe taking the evangelical approach like this pastor did (Source 1) makes the explanation seemingly fit which I am grateful for. I'm always going to rely on how Jesus fits in every Bible verse now when I'm studying it.

I take notice that the serpent's head and the Son of God's heel are on two opposite spectrum. A source mentions that the heel represents the lowest corporeality and the head is the dominion of evil or at its highest peak (Source 3).

In my opinion, Satan is struggling because of the Son of Man and being brought low as the Bible mentions the serpent crawling on his belly to the dust; all that Satan could muster in his strength was to influence the sins of man to nail Jesus on the cross which was not enough to bring an end to God's salvation.

I just added in the part about the difference between Christ's heel and serpent's head. The real significance of the heel is that the death on the cross meant a nail being driven through the heel which is a very painful death.  Check out Source 4 for a picture on crucifixion bones.

At Satan's heyday, the Lord promises that he will be defeated as already foretold in Revelations. The verse says that Christ will crush the serpent's head. This verse is prophetic to me in that Jesus shall defeat sin and that God has already fulfilled His promise of bringing man salvation.

Source 2 gave off this excellent theme that works in how from this verse, we can infer that there are two types of seeds working in us; basically we have knowledge of good and evil and that ultimately we get to choose to entrust Jesus as our Savior.
