Life very certainly, is Predestined .. . But ... we have the Absolute Control, over our Fate ...
You see, things, belong to the Owner ... Right ?
... And we, belong to God... God, The most Gracious and Kind, Owner... our Creator, Who Is, A Just Owner.
So while it was simple for Him to make us Follow His Desired to the dot, like Technology, follows the Design... He Granted us "The Correct Way of Life" ... and the Ability to Distinguish, between Right and Wrong, and the Limbs to enforce our Choice, into Actions.
And Being Most Kind, He Granted us the absolute Freedom, to choose Freely, between Right and Wrong so that humans could Freely Follow one of their Free Willed Choices, as the Way, of their Life ... absolutely without any Hinderance.
The fools, who think, they fell out of the sky, and do not believe in God's Creating them, think, they can do, as they Like.
So the Life we live, is a Life of our free Choice ... and so we think, we are doing everything because of our Money or Will Power ...
But the Truth Is, that on The Certain Day, we will all be Asked of our Doings.
Thus, we write our Destinies, with our own hand ... by Following the Right, when we have the Power to follow the Wrong way in our lives ... thus, we ... the Believers ... in a God, who may not make us win Lotteries ... are the real Winners in Life.
