Everybody talks about coincidences. Rest assured there are none. If you believe there are coincidences, then you have failed to learn that God is deliberate in every way. It didn't "Just Happen". God is the Master and he does have a plan. I believe that so called "coincidences" are presented to us as a means of drawing our attention to something or someone. Why this happens is not always immediately known. However, if you are patient and persistent enough , most times the "why" becomes transparent.
When I hear people say "What a coincidence!", I am reminded of the atheist, and evolutionist who believe that man began as an amoeba and through a series of evolutionary phases was transformed into his present state. I have to laugh at the absurdity because any idiot can look at the human body in its complexity and know that it is impossible to have evolved into its present state. Do they honestly believe that the human body is a coincidence? Furthermore, who created the amoeba?
