Really, really bad things happen. Life is so fragile. God can call us home at a moment's notice. So many things that we think are important, are not that important. Seeing all those cars and homes being swept away is sad, but knowing many lives were lost is SO much worse.
Life is precious and should be valued. Every day, every moment should be spent loving God and loving others. God is big...really, really big. People will question how a good God can allow this to happen.
We live in a fallen world. He tells us in Scripture that these things will happen. This isn't our home. He is preparing a place for us where there will be no more tears or pain. These things should point our eyes upward to our true home and help us to want to live in anticipation of that time when every knee will bow and every tongue confess that He is Lord. {Romans 14:11}
We are strangers and aliens. Time is short. Use your time wisely being salt and light in a dark and decaying world. Love other people and serve them, especially your family. Let your neighbors see Christ's love through you and remember to "Be not afraid!" for He is with us and will never leave us nor forsake us.
