Not knowing what was coming over the horizon!I think that's a wonderful reason for the world being round! The creator wanted us to have surprises! I vaguely rememeber that the title of a book I read a very long time is "God of Surprises"!
There are people who plan every day, every moment of their life so very carefully. They leave little room for the unexpected. Naturally, they seldom have the joy of being surprised by the serendipitous.
I have had delightful surprises. For example, I think of having something. I don't have any clear idea how I am going to have it. Belive it or not, within a few days, I get it-- without any effort on my part. It just turns up -- in unexpected ways!
That's why my faovurite title for God is "Provident God" - a God who forsees and provides!
Naturally, such surprises makes one grateful. Try being grateful, it will transform your life!!
