God has NOT placed most of us in the place we are. Our bad decisions and choices have landed us here. However, if we're truly Christians and give our life to God while confessing our sins, He will act and guide us where we need to be. He may not 'fix everything' as most of our current situations took some time to create.
“Believe in God; believe that He is, and that He created all things, both in heaven and in earth; believe that He has all wisdom, and all power, both in heaven and in earth; believe that man doth not comprehend all the things which the Lord can comprehend” (Mosiah 4:9; the Book of Mormon: Another Testament of Jesus Christ). http://lds.org/scriptures/bofm/mosiah/4.9?lang=eng#8
