I'm a Roman Catholic but there are times that I question God's existence. Am I the only one who think this way?

Almost every religious individual, and all of the great philosophers from Aquinas to Kant question their faith or god at some point, so this is nothing to feel ashamed of. Remember, Jacob, who wrestled with angels, was later renamed Israel - translated, means "He who struggles with god". Questioning your faith does not make you less faithful, it instead makes you more well versed in your understanding of the miracle of life. It is the responsibility and journey of every religious person to contend with God, Existence, and the vicissitudes of life, and to emerge from each struggle with a greater understanding of their life.

No! You're definitely not alone in your thinking! Personally I think it's good to be able to question things;- even God's existence. It allows us a sense of curiosity and to try and see the bigger picture - what does his existence mean to you? What might God look like? How important is having that spiritual connection in your life? How does that fit in with the Roman Catholic beliefs? How do you feel about his existence? Sometimes and sadly questioning God's existence when you're part of a religion can be frowned on - but ultimately this depends on the people around you and the mindset of everyone. We all have different beliefs and that's okay.

Nope! I'm a Protestant, Free Methodist Christian to be exact, and I do the same despite feeling the Holy Spirit and seeing God's love. I question His existence more than I'd like to admit, but I know the Enemy's just trying to work against me. I believe in God's existence as much as I believe in my own

It certainly is human and rational to question things. You think for yourself and you are entitled to ponder anything you want. Having doubt is not something you have control over, is it? You can't just wake up one day and decide you will no longer have doubt. So if it is out of your control you should not apologize for it, especially since you are not harming anyone.

No, Not only you. Humans have a deep thinking ability and naturally humans tend to think with facts. So, this is a natural thing.

As a born Orthodox Christian I can tell you that you are not alone, not only you are not alone in your thoughts but there are millions of people having these kinds of thoughts at this very moment.

I was once Roman Catholic. In my experience, many people feel this way, especially younger people. But questioning your faith can be a healthy thing. Keeping faith isn't always easy either, so much trust is put on belief, so it's not strange to feel this way :)

No, I am a (practicing) Roman Catholic as well! I don't know how old you are, or how involved you are in the Church but if available, I HIGHLY recommend you to attend an ACTS retreat! They have them for women, men, and teens; and I have watched them transform peoples' lives. They are very popular at nearly every single parish where I live but they are now starting to spread to Rome which is super cool! If you have gone on one already, it's still normal for your light to sometimes burn out. Some super cool things to watch that help, and AMAZE, are looking up videos about Eucharistic miracles on Youtube. they are the coolest, and really help you believe that receiving the Eucharist on Sundays IS the Body and Blood of Christ!!!
