The Least of These

So...I am about to begin a new chapter in my life: my career. I never thought I'd be here but now I am, facing the unknown. I am about to begin my life as a nurse, and more specifically a neonatal intensive care nurse. Part of me cannot wait to jump right in and get started. The other part of me is wondering what exactly it is that I have gotten myself into. I seek refuge in my favorite scripture that has guided me through nursing school and has outlined my mission for my life as a professional nurse:
"When the Son of Man comes in his glory, and all the angels with him, he will sit on his glorious throne. All the nations will be gathered before him, and he will separate the people one from another as a shepherd separates the sheep from the goats. He will put the sheep on his right and the goats on his left.
"Then the King will say to those on his right, 'Come, you who are blessed by my Father; take your inheritance, the kingdom prepared for you since the creation of the world. For I was hungry and you gave me something to eat, I was thirsty and you gave me something to drink, I was a stranger and you invited me in, I needed clothes and you clothed me, I was sick and you looked after me, I was in prison and you came to visit me.'
"Then the righteous will answer him, 'Lord, when did we see you hungry and feed you, or thirsty and give you something to drink? When did we see you a stranger and invite you in, or needing clothes and clothe you? When did we see you sick or in prison and go to visit you?'
"The King will reply, 'Truly I tell you, whatever you did for one of the least of these brothers and sisters of mine, you did for me.' " Matthew 25:31-40

So...my question is who exactly are "the least of these"? I hope to seek out the least of these as a neonatal nurse. I hope to love and comfort them the way that Jesus would want to be loved and comforted. I know that the Lord has put me at this post for a reason, and I intend to serve him to my utmost ability. Thank you to all those who have supported and loved me throughout nursing school. I hope to use this blog to provide you with little moments from my journey as a NICU nurse.
