If you really have to ask, that tells me you don't study much.....
I will give you one of numerous scriptural proofs to the validity of my point.....you can look the rest up for yourself!
Jeremiah 1:5...BEFORE I formed thee in the belly I knew thee: and before thou camest forth out of the womb I sanctified thee, and I ordained thee a prophet unto the NATIONS....
It takes more than just reading the bible or a few scriptures to learn the word of God and understand the deep nuggets to be found.......I suggest a more in depth study friend as the bible makes it clear that God knew all things before he cast down the word...including the above thoughts that you are rejecting and questioning......!
A driver of a massive garbage truck lost control of his vehicle. The truck jumped the curb, hitting a couple and a 23-year-old man walking on the sidewalk. According to a New York City newspaper report, the couple was killed on the spot and the young man was knocked unconscious. When he woke up and saw what had happened, his first thought was: I can't believe this is happening. Please, God, let me get through this. He said, “It wasn't my time to go.”
YOU have likely heard similar stories. When a person narrowly escapes a disaster, people say, "It wasn’t his time" but when someone dies in a freak accident, they conclude, "His time has come" or "Its the will of God" Whether they attribute the outcome to fate, luck, destiny, or God, the rationale is basically the same. Many people believe that events in their life and the outcome are predetermined and that there is nothing they can do about it. And this type of reaction is by no means limited only to when death or accidents are involved, neither is it limited to this day and age.
The ancient Babylonians for example, believed that human affairs are influenced by the stars and their movements. They therefore looked to the heavens for signs and omens to guide them. The Greeks and Romans worshipped goddesses of fate, whose powers to dispense good and bad fortunes at times seemed to overshadow even the will of their chief gods, Zeus and Jupiter.
In the Orient, Hindus and Buddhists believe that what a person is presently going through is the result of what he did in a past life, and his actions in this life will determine what he will experience in the next life. Other religions including many churches in Christendom also give credence to such fatalistic beliefs by their doctrine of predestination.
It is not surprising, therefore, that even in our supposedly enlightened and objective age, many people still believe that their situation in life, the outcome of their daily affairs, and their ultimate destiny are all controlled by fate and that there is little they can do about it. Is that how you feel about life?
Are life's events and incidents, successes and failures—even birth and death—really predetermined? Is your life ruled by fate?
Jesus Said at (Matthew 6:3) do not let your left hand know what your right hand is doing; God also wants to be surprised to the fact what happens in our life, and choice we make come from are heart. Knowing what future has in itself has limits. Not saying God has limits.
If you had three closed door in front of you. Do you know whats behind all three? its not until you open one of them to find out what lies behind. So he chooses to not know. Predestination is not at play in every aspect of Our lives.
