This passage makes me think of the story of Jairus, the synagogue ruler from Mark chapter 5. Jairus came to Jesus because his daughter is sick and is dying. He thinks that if Jesus can get to her before she dies He can lay hands on her and heal her. Unfortunately, before they could reach the place where his daughter was, she died. A messenger came to Jairus and told them it was too late and they didn't need Jesus anymore.
Ignoring this message Jesus looks at Jairus and say, “Don’t be afraid, just believe.” Nothing elaborate or long winded, just simple and to the point. When they got to the house everyone there was crying and wailing loudly. Jesus said to them, “Why all this commotion and wailing? This child is not dead but asleep.” They laughed at Him and ridiculed Him for saying this because they all “knew” she was dead. So Jesus put them all out of the house and turned to the girl. “Talitha Koum!” Jesus said to her, which means, “little girl, I say to you, get up!” She then proceeds to get out of bed and walk around as if she had just been sleeping.
Here in Luke where we see Jesus tell us that our God “is not the God of the dead, but of the living, for to Him all are alive.” It brings a different twist to this story of Jairus. We realize that Jesus wasn't just speaking in faith when He said when He said she is not dead, but merely sleeping. He actually meant it. To God all are alive. Her spirit was never dead, her body had just fallen asleep and Jesus was there to wake it up.
In the same way our earthly bodies may “fail” or fall asleep, but that is not who we are. Our bodies are just a shell to house our spirit while we are here on earth. Who we are is on the inside, in your heart. Proverbs says, “As water reflect a face, so a man’s heart reflects the man.” God created us as eternal beings, in His image, so when we pass on from this life we don’t die, our bodies just go to sleep. Our bodies are fragile, but our spirits are eternal.
When you begin to see things in the eternal perspective as Jesus saw them, it will be much easier for you to have faith for miracles. All the miracles Jesus performed where already a reality in heaven and He was just bringing heaven to earth, one “miracle” after another. Now it is our place to bring heaven to earth through our actions. Even to the point of waking the “dead” if needed.
