...it is you who choose not to believe God
Belief is not a "choice" any more than love is a "choice".
Sure it is. I can choose to treat someone kindly or be patient with them to an extent, even with those who many would consider as not deserving such mercy or compassion.
But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, self-control; against such things there is no law.
I can choose how I am going to respond to you, with love and compassion, with hate and malice, or somewhere in-between.
YOu CAN "choose" to follow someone or "choose" to DO or not do some particular thing.
You can't simply "choose" to believe or disbelieve in anything.
Sure you can. You can weigh the evidence and reasonableness of a position or worldview and change your beliefs.
I can't stop believing in air.
I can't stop believing in water.
That is because the belief is reasonable, obvious, and logical to believe in, plus such a belief corresponds with your senses.
I can't "choose" to believe in Santa Claus.
Yet some do choose to believe in him despite the evidence against his existence.
I can't "choose" to believe in unicorns.
Some people do choose to believe in unicorns based on a feeling or what they see as evidence. When you hear something you have a choice of whether you are going to believe it or not. That may depend on how reasonable you find the evidence.
Belief is simply NOT a "choice".
It can be. It is whether the belief you place faith in is reasonable, unreasonable, or blind. That is the question. Granted, our culture, our environment, our family, our subgroups, may radically affect what we believe.
It is our core beliefs that are not easily rejected or dislodged. Those beliefs require a paradigm shift. Upon those beliefs sits the whole foundation of beliefs. The outer core of belief is constantly changing and being modified.
