There are those people who claim to be atheists ( they believe there is no God) but when you challenge them on their beliefs. Oh, I forgot they don’t have those? They simply have no argument and they know it! At its core isn’t any belief come from God?
Meriam Webster Definition of Belief: a state or habit of mind in which trust or confidence is placed in some person or thing
So they are hypocrites when they say there is no God. If there is no God then why do they spend so much time denying there is a God? One would think that since they believe there is no God the topic should never cross their mind! Yet it does.
One of the arguments you get is that you can’t prove God exists? (Of course, believers can very easily.) They fail to mention they can’t prove there isn’t?
So as believers the question then becomes how do we with this issue as it comes up? I think an all-out verbal attack is counterproductive.
First of all, pray for them. In many ways, many atheists are trying to prove their point by watching you fall on your face! Always keep in mind that Satan is at work here by presenting this person into your life. Then you need to let God do his thing!
