Here is the thing about belief and faith. It has nothing to do with investigation, education, documented facts, essays, collected life works of devoted believers. Denominations, statements of belief, pretrib, posttrib, which version of the bible you read.
It has to do with you, believing that God exist and closing your eyes and praying to him. No, let me clarify. Talk to him, remembering that you are talking to the creator of the universe. He is God, He can hear millions of voices and know each one. He can hear you. He created you. Don't get hung up in your inability to comprehend God. You can't and never will.
Just pray, if you believe in his existence and wait. He will answer you. Maybe in words that you don't like but if you take the time to consider what you are being told, you may be surprised.
God looks at the intent of your heart. Let me say this again. He created you, he loves you and he wants you to trust him. Unconditional.
Get to that point when you give it all up, put it in his hands. You will be surprised, shocked and will have discovered the true understanding of why you can now sleep at night, because you have God.
Doesn't matter which church, denomination, just go. Join with other believers. Worship, pray, sing to God.
You go, and just say"I am here to worship you God"
