We are made of a spirit and a physical body. Before our physical bodies were created and we were born, our spirits lived in Heaven with God who is the Father of our spirits. We were there a very long time, maybe even thousands of years or more. We loved our Heavenly Father and wanted to become like Him so we learned from Him and progressed in our learning until we were finally at a point where He could test us to see if our hearts would still choose Him and His ways even in a setting where there were many other options. So, He sent us to earth where we would gain a physical body and be in an environment full of other options. Our memory would be temporarily wiped clean of our time in Heaven, yet when we would encounter truth - pure truth just as we had known in Heaven - something inside our spirits would stir and we would stop and wonder why it seemed familiar to us. IF, we embraced that truth then another truth would be put in our path, and another, and another, until we had fully come to a spiritual rememberance and realization for ourselves that we are indeed passing the test and still choosing our Heavenly Father's way.
So, what does this have to do with a mosquito? Well, all of the creations were made with specific roles to play in providing this opportunity for our testing. The mosquitoes were commanded to pester us. They are only being obedient to God when they perform that duty. The weeds were instructed to grow in our gardens and be a hindrance - they love God and are being perfectly obedient. The seasons with the blistering sun and the bitter cold winter are only being obedient to the pattern God commanded them to follow.
Since Adam and Eve left the Garden of Eden man has battled all of these (and more) challenges to their daily survival. There comes a change of heart when we recognize the humility and faithfulness of a mosquito trying to suck our blood or a squash beetle trying to kill our zucchini plant. When we recognize their obedient example it is hard to think of them as an enemy that needs destroyed. It is all a test to see if we will respond with anger or if we will patiently learn to exercise righteous stewardship over them. I like this talk with the story about Joseph Smith and the rattlesnake.
Just maybe this is the beginning to bring about Isaiah's words:
Isaiah 11:6
The wolf
also shall dwell with the lamb, and the leopard shall lie down with the
kid; and the calf and the young lion and the fatling together; and a
little child shall lead them.
