I dearly love this chapter as for me, from my point of view, I see that this is a common strand that moves through scripture and has many functions in revealing Y'shua (Jesus) to us. At the beginning of this chapter, Elijah (My Elohim is Yah) is told by Yah that he is to prophecy to Ahab neither dew nor rain will come until I say so. Then he is told to go to a certain place named Cherith (or Keryith which means cutting or to cut, make a covenant) and remain and Yah will provide for his food (through the ravens) and his water (by the brook).
I see the fact that the very food elements are mentioned tells me that the significance of what they are has meaning. Bread and meat. Y'shua refers to himself as the Bread of life and as meat for the believer (John 6). Meanwhile the water is a very common symbol for the Spirit of Elohim representing the faith of the believer. So in my perspective we see the same elements as we saw with the children of Israel while in the wilderness, bread (manna), meat (quail) and water (the rock or Y'shua). The first 'miracle' then in this story for me is the sustaining of the believer by Elohim.
Next comes the brook running dry and the command to go to Zarephath (refinery or maybe the place of refining?) and there he will meet a woman who has been prepared for his support. Could this tie to Isaiah 48:10 and to 1 Peter 1:17 or James 1:12? Who is to be refined here, Elijah or the woman...or both?
So he meets her and instructs her to make him some bread and provide him a drink. She basically tells him that her hope is wasting away (because of the drought, like Revelation 3:8?) and she is preparing to die along with her son. Still Elijah contends that she should take care of him first and then she can take care of herslf and her son. Isn't this in keeping with Philippians 2 and 1 Thessalonians 5? Wouldn't her doing as she has been told be a sign of her love and obedience, her faith in the ability of Yah to meet her needs and to give her the desire of her heart?
The flour and wine (Y'shua, Spirit of Elohim) never run out, they are always there and always able to meet every need. Does that mean that each day we as believers are experiencing an on-going miracle? Every day? Hmmm. Guess that would depend on what you consider to be miraculous. Does it take a proverbial lightening bolt to make something miraculous? Is it a miracle as determined by the result of the action/event? So why did Yah have Elijah go there in the first place?
Next, the woman's son dies. She has faith, especially after having seen her faith rewarded by the 'miracle' of the flour and wine and how it continued for such a long space of time. So she reacts towards Elijah how? "Did you just come here to make me see my sin and cause my son to die"? or "Are you just here to make my life worse"? To test me? To try me? (back to Peter?)
Elijah then does something kind of strange...or something prophetic? He goes away with the boy and then "lays" on him? That can have a lot of different meanings but it causes me to think about his mantle. There is power in that mantle. Elisha will also raise a man in the same fashion and then a dead man will rise after touching Elisha's bones even after Elisha dies. I think his mantle (talit) would be on his bones as is customary.
Who else will do this? Y'shua will do this when He raises Yairus (Jairus) daughter. He will place his talit on her (after the woman with the issue of blood has touched the same talit and power emanated from it to her) and will raise the girl to life. Faith brings about life, life more abundant. Faith helps us down that path which Y'shua is, the way the truth and the life.
I didn't answer your question directly as I think there is so much more to it then the determination of what constitutes a miracle. I see it as a part of something much larger and interwoven through scripture, as a part of the very fabric of who the messiah is as opossed to what the messiah does.
I apologize if I haven't done your question justice. I went with what I felt the Father had for me to say.
