Just because you haven’t seen God with your eyes, doesn’t mean he isn’t real.
He says he makes himself known to those who seek Him. If you seek me with all of your heart, I will be found of you he said.

Those who close their thoughts and close their hearts don’t get to experience his awesomeness. They go through life with a closed heart. He warns in His Word to those who have, what he calls, an evil heart of unbelief in departing from the living God.

Seek him with all of your heart! He made an everlasting covenant through the blood of his Son. He isn’t a liar.
The attitude of your heart means everything. He is the best friend you will ever have. He loves you sooooooo much. He is on your side. And when he shows you how real he’s is, it will FLIP YOU OUT!

He meant what he said. For God so loved the world, he gave His only begotten Son, that whosoever believes in Him, should not perish but have everlasting life. He is the only one who defeated death on your behalf. No one else can rescue you from the power of death in the end.
