Spiritual Lessons-- God sent us his Holy Spirit, the Comforter, to teach us all things. I think that our Heavenly Father, as would most fathers that truly love their children, would rather we hear the good things he wants to teach us, and then live in them with the joy and gladness he intended.
However... and this is a big however, we often decide to do things that are not healthy for us. This is true as the human race, and for us as individuals. Sickness, pain, and death all came with the fall. Remember what God said, 'Do not eat of the fruit of the tree of the knowledge of good and evil, for....in that day you will surely die.' Of course the serpent twisted it around...'you shall not surely die, God knows in the day you eat of it you shall be like Gods!'
Well thanks ya nasty snake... but I have to admit, last year when I went through a traumatic winter of flu and stomach ailments I did learn a lot. For instance, if a fast food burger tastes like drain cleaner--spit it out. If you are in a strange town all by yourself--know where the hospitals are. And if you only have a cell phone and it has no signal, calling 911 doesn't work.
But most of all I learned that I didn't want to be alone. Back to Genesis--'It is not good that man is alone.' So he made woman. I met someone special, gave up my on-the-road job, and found peace in my life. Spiritual lesson learned--spit out the burger and love the woman god gave me.
