This is all my opinions.
My advice, and I don't know if this will help because it's a different approach than what you are doing, but put the religious books aside for a minute. They are supplements to your faith not a replacement of it.
I'd write down all your priorities in your life without thinking of any religion associated with it (unless, like Christianity, it is a priority).
You can list concrete things like family, self, environment, helping others, and things of that nature and others not limited to.
What do you do and value on a daily basis? Are you school oriented? Work oriented? Do you have a goal or calling
even if you don't know what it/they are?
What are your morals?
What do you consider right and wrong?
Then go to the religious books and think reflective thoughts. How does Christianity relate to my priorities and morals? Do I
want them to be my priorities even though I have different ones? Am I willing to sacrifice some of my values to take up those of Christianity?
That's another challenge that may be hard for you. If you take up a religion, in my opinion, there are some beliefs and traditions that you may not be familiar with or are uncomfortable with.
A religion that may click with you isn't one that will pull you away from the religion because of what you are not comfortable with but it will let you want to overcome those challenges and understand what they mean when they say X and
how does it apply to your life.
That's another thing thing about religion. When you have priorities and values, they usually apply to your life and actions not just thoughts. The same with religion. If you find a religion that reflects what you belief and set as a priority, are willing to apply these beliefs or actions to your everyday life?
How do you view religion? Will it be part of yourself or something you are interested in?
On the other hand
If you already have priorities and morals, why do you want a religion? Do you like structure? If not, maybe stick with following what you value, write it down, and put it to action.
You can still believe in god or a deity without religion.
