There is a ladder which extends from Heaven and reaches even the lowest points on Earth. Loyal angels constantly scurry down the ladder to fulfill their Divine mission, and then hurry back up to await new orders. No matter where you may be, the angel-filled ladder will shadow you; God's protection will always be with you.
There are no coincidences; whatever happens is orchestrated from Above and implemented by the angels descending the ladder.
The Baal Shem Tov explained that not only is everything by design on the local level, but every happening is an integral piece of a huge jigsaw puzzle.
The "butterfly effect" is a perfect example for this point. Every occurrence, as trivial as it may seem, is part of God's grand scheme which encompasses all of creation. The finite human mind, or the most powerful super computer for that matter, cannot begin to comprehend how the trillions upon trillions of events from the dawn of time until today can all be part of a singular vision and plan. I daresay that if we did understand, we'd be God ourselves...
God makes the choices for the entire world, but He empowered each of us to makes the choices in our own lives; our own "worlds". He made known His method of managing the world, so that we can adopt this modus operandi in the management of our own lives.
When faced with making decisions, we often take the "local" route in order to arrive at a choice. The primary factors which determine our choices are typically short-term convenience and expediency. If we are to be God-like we must train ourselves to look at the larger picture and think on a larger scale. Our major goals and aspirations must be the dominant factor when making any decision, big or small. Will this action bring me closer to my goals or not? Is this deed part of the dazzling picture which the puzzle pieces of my life are meant to complete?
