Gravity is a force of nature and is a good example to give an atheist that doesn't believe in something he cannot see. You can bet your a$$ he believes in gravity.
Yep. You can't see gravity, but you know it exists because you can see and feel its effects.
Believers can see God in many things, including creation itself (which EVERYONE who isn’t blind can also see), and believers know God exists because they can feel the effects of the existence of God.
