A trajectory is a path, progression, or line of development resembling a physical trajectory. A physical trajectory is a curved path which something takes as it moves through the air or through space. The idea behind space flight, for example, is that if enough force is propelled onto an object to move it to a place where the force of gravity isn’t as great, the object can continue in motion. A trajectory is determined by the projectile’s influence. The projectile is the object that is moved, dropped, thrown or even fired -like a gun or a rocket- and its main influence is the force of gravity.
A projectile’s path can only be influenced by gravity. What stronger force is there on the planet that we live on? Gravity can never be defied, it has to be overcome. The only way that a projectile to fly is to be lighter than the pull of gravity or to have more force to propel over the force of gravity. The fact that an item flies does not mean that it contradicts the laws of gravity, just that it does what is necessary to continue its movement against the pull of the atmosphere.
Trajectory planning must be thought out, calculated, and prepared. Everything is weighed to determine the path and destination. The timing, the target point, the ability to avoid obstacles and collision makes the planning difficult but possible. The most effective determinant in the trajectory of a projectile is what is called the “manipulator.” The manipulator determines the force behind the projectile and the location of the starting point of the projectile.
The path of a trajectory is never straight. Because of gravity and other factors like wind gust and the form of the projectile itself, the path is often curved. The path can vary in so many ways. The important thing is the beginning point and the end point. The main factor in a trajectory is that the projective ends up at its designated source.
In life there are so many avenues and directions that we are pulled in and so many things that carry us in directions that we don’t want to go in. If the road in life could go in a straight path life would be very predictable, and at times boring. Life however is a journey. Our journey consists of many winding roads, turns, curves, hills and valleys. There are also obstacles that attempt to deter us from reaching the end point of our destination.
What we must rely on is the fact that the source of our manipulation is stronger than the forces and the obstacles that stand against us to prevent us from our purpose. The scriptures indicate that we were chosen in him before the foundation of the world. It is also written that those whom GOD has known in advance, he has justified and are conforming them into his Image and likeness. Because of this, ALL THINGS are working together for our good. The “good” indicates that our ultimate destiny and purpose of our existence for being joint heirs to GOD’s Kingdom according to the previous chapters in Romans 8.
It is written
“For I know what plans I have in mind for you,
says YAHWEH ,plans for well-being, not for bad things; so that you can have hope and a future.” (Jer 29:11 Complete Jewish Bible).
Our lives at times can seem so out of control because of the variances of winds, and obstacles that can seem to offset our journey. All these things that we face have been pre-calculated by the Manipulator and Creator of all things that are working for our good. The GOD of All Heaven and Earth, whose name is YAHWEH has ordered our steps and have set us on a path for ultimate victory. The path also creates in us a character of greatness and fortitude where we are able to govern in the Kingdom of The Most High.
Our problems, failures, anxieties, insecurities, past, present and future decisions have all been weighed out and predetermined before the Manipulator of our trajectory even set us in motion.
Every day we are set out on the path to greatness. Because of this, every day we must know that “All things are working together for the good to them who love GOD, to them who are the called according to his purpose.” Rom 8:28
