If god proved his existence, how would that affect mans free will to choose to accept/love him?

god should be capable if he is all powerful, and he should be willing if his prominent desire is to obtain our love and acceptance. I believe by making himself directly observable to everyone (he could make it so we know its god without blowing our minds if hes all powerful) he would be setting the best conditions possible to gain our love and acceptance. we could still choose to reject him so free will applies. the best conditions to genuinely love someone is to interface with them directly, its easier to come to love someone whose existence isnt debatable. This would end atheism, agnosticism, and unite all relgions to the 'right' religion -gaining god more followers. by not proving his existence he has much less followers. why not prove he exists, shouldnt he know exactly what sort of evidence every individual needs to believe he exists?
