Alright :3
As per the norm with most of my critiques, this is going to be very long.
Honestly, I feel like in the future, you'll be having a hard time finding supporters of your comic and your faith through your comic, and this is for two identifiable reasons:
1.) The target audience. Finding very faithful Christians on Facebook? Easy as pie lol Finding very faithful Christians on Tapastic? They're there, and they're tough to find, but they're there alright. So you're gonna have to really dig to find the target audience that you've made this comic for. I know you said it's "for everybody, teens and adults, Christian and Non-Christian", but I think we both know the only people who are going to appreciate the comic to its full extent are the Christians, and the very, VERY faithful Christians at that (when I say "very very faithful" I mean the difference between Christians who just go to church once a week and do what they can in a comfortable fashion and Christians who have fully devoted their lives to their beliefs and make it a point to try and spread awareness of their religion; nothing is wrong with either of those).
2.) The way you deliver your content. This is the part where it's going to start sounding a bit negative, but bear with me here, it's something I want to say because I feel it will help you out, and it's the biggest part of my critique.
The way you deliver your content is . . . TBH, it's the same way Jehovah's Witnesses go around knocking on people's doors, and the same way church groups leave comic book pamphlets in public restaurants and on public park benches to try and convert people (don't believe me? Check this out lol We've already found THREE of them at Starbucks where I work and they're all different and SUPER weird and uncalled for lol).
It's very forceful, you know? You're almost spoonfeeding people the message you're trying to get across, and when you do that, that's what makes people want to slam the door in your face, or crumple up the pamphlet and throw it away, or take the comic booklet to the backroom and laugh about it before going back to work. You're trying to force people into your religion, when you should be giving encouraging reasons why they should decide to do it, on their own.
And that has nothing to do with what people believe in, believe it or not! People have converted all the time, but you really need to give them a reason to. Most people have either switched or lost their faith due to an extreme reason that they've built it on; not because they just "felt like it" and now they need a few set-ups to show what could happen to them if they don't accept God into their hearts, because that's just what we call the shock factor; it didn't work for the D.A.R.E. program in middle schools, it's not going to work for churches trying to turn more people to their faith.
And yeah, I get it. It can be tough to try and spread awareness of your faith without spreading information in a way that sounds like a PowerPoint presentation, or showing your faith in a negative light.
You want to see a good example of a "religious" comic? Go read Happle Tea. It commentates and pokes fun at several different religions and religious groups, including the Greeks, Nordics, and yes, Christians. Does it paint a bad picture of the religion it's portraying? God no. It presents content and tells jokes in a way that's fresh and makes you giggle and think about the religion, but not criticize it.
Here's a Christianity example. Note that there is some language but ti's not excessive, literally just the use of the word "shit" which of course we wouldn't imagine God using but it's certainly chuckleworthy when he does (I mean, God's the last person we'd expect to say "shit" lol)
Here's another one about the story of Moses being let go by his mother into the river:
It certainly paints a different picture of "religious content". But in a funny way that works when you present it as a comic; as @ghostnxs stated, people read comics to be entertained; even if it's educational or trying to raise awareness, you can do it without forcing your beliefs into a comic that's just trying to force its message.
I know this might not be what you're trying to achieve with your comic, but keep it at least in the back of your mind, as right now, as painfully honest as I can be, your comic currently reads as a campy, "here's how you cross the street" instruction manual. You can get your message across without making it obvious that God loves everyone, or making everyone's life a living hell until God comes in, because, as an honest person who used to be Christian until losing their faith, I can guarantee that 99% of people who convert to Christianity do it out of interest in the religion and going, "well, I don't believe in anything else, but I can believe in God because that's meaningful to me and it gives me a little more purpose in life" or because "my family raised me with their beliefs, and I've never had problems with it yet, so I guess it's alright", and people tend to lose their faith for the same reason - "well, God just doesn't make sense to me, and I can find purpose in life on my own two legs, or with a different god who shares my beliefs" and "well now that I'm separated from my influential family, Christianity just doesn't seem like a right fit for me."
It's not always hanging off a cliff and being saved by him, or losing your wife and kids and job and having your life go on a downward spiral until you accept him into your heart. Yes, this has applied to some people, but in the real world, converting to religion just doesn't happen like this like some kind of magical transformation that changes everything and makes things automatically better. You have to do some of the work yourself, for yourself, and that's a lot more of a realistic approach to converting to a certain religion and using it as a stepping stone for bettering yourself as a person, whether it's the stories told or the morals that are taught in it (I'm not Christian, but I definitely use some of the lessons taught in the Bible as a way to live; treat others the same way you'd like to be treated, be loyal to your partner, etc. because those are just proper morals that teach us how to respect and love and treat each other with comfort and care. It's all about love, baby.)
So that's the end of my super long critique that I was only planning on making a few paragraphs. I'm not gonna tell you how to draw your comic, because you already seem to have your own thing going on with it, but keep some of the stuff I, as well as others, have said about how you're presenting your content in the back of your mind. You're an artist, you're creative, so I'm sure you can think of a great way to spread the message and raise awareness without forcing it down people's throats. Read some of the comics we've suggested, like Happle Tea, and Archangel, etc. You don't need to like these comics, but use it as an educational source.
Instead of telling people they'll die if they don't accept God, or lose everything they have, or lose everyone they love, etc. tell people all of God's messages about love and acceptance and tolerance for his children and forgiveness of your enemies. Don't resort to the scare tactic. Show people it's all about
