To what degree is God responsible for some people not believing in God? Does God not want these people to believe in him? If God can do anything and knows everything, then he certainly knows precisely what it would take to get an atheist to believe he exists. Yet he does nothing. Why?
Because the responsibility to seek God belongs to us. God will provide exactly what you need for belief, but it is your responsibility to Ask, Seek and knock for the Holy Spirit.
5 Then Jesus said to them, Suppose you have a friend, and you go to him at midnight and say, Friend, lend me three loaves of bread;
6 a friend of mine on a journey has come to me, and I have no food to offer him.
7 And suppose the one inside answers, Dont bother me. The door is already locked, and my children and I are in bed. I cant get up and give you anything.
8 I tell you, even though he will not get up and give you the bread because of friendship, yet because of your shameless audacity
[e] he will surely get up and give you as much as you need.
9 So I say to you: Ask and it will be given to you; seek and you will find; knock and the door will be opened to you.
10 For everyone who asks receives; the one who seeks finds; and to the one who knocks, the door will be opened.
11 Which of you fathers, if your son asks for
[f] a fish, will give him a snake instead?
12 Or if he asks for an egg, will give him a scorpion?
13 If you then, though you are evil, know how to give good gifts to your children, how much more will your Father in heaven give the Holy Spirit to those who ask him!
It is the Holy Spirit that gives us our "proof." We ask thru prayer, we seek in the bible, church and places like this, we knock till we get what our heart wants.
