I also do NOT believe in coincidences.
For me, they are evidences that God is in control: sovereign.
Whether He uses angels or direct Will to show me doesn't matter
to me.
There is more than one reality (that which most people tend to live within.)
A congruent aspect of more than one reality proves the greatness of God to me.
Quantum physics has proved the "observer effect." This is where what you believe you will
see, is what will be. (Not just what you think you see, but what actually becomes.) It is
the substance of what others call "faith."
When people pray for the same thing, it happens. This is not only God's Will and strength, imo
but science. What some term a "coincidence" is not happenstance at all to me, but a
"meeting of the Spiritual natures" of mankind and God.
(I hope this is not too close to guideline limits.

Please let me know if so, and allow me to edit. )
