I am reminded recently of the truth that your life is not in your hands. God holds your life and the length of it.
My mother passed away quickly recently. One moment she was having breakfast with me and the next she slipped into eternity to be with the Lord.
Hence for all of us: be always ready to meet the Lord. Do what He has assigned you to do one day at a time.
Plan that you may live long but live each day as if it may be your last.
