I am going to preface this by saying that there is no recipe for belief. Belief must be a part of your own will, and your own choice. It also depends on what to believe. Do you believe in God in general? Are you only warming up to the idea of a God? What is it you exactly want to believe? The how for me was simple. Well, it was a simple decision on how to find out, but it was by no means a simple path. I read. Lots. I finally formulated a conclusion that God had many messengers, but that was changed, and I cannot explain how, but I no longer felt right praying to Krsna or others. And I prayed to Christ, and I asked the Saints to pray for me. But that was me. Then I read about different Churches and found which one actually fit my beliefs. You need to decide for yourself how to approach the subject. I used this quotation in another thread for some other reason but I think it is still applicable: From the second Sura in the Qur'an, "[256] There is no compulsion in religion". Religious/spiritual belief comes from within from the yearning human soul, as well as from a divine call. Only when both meet will there be a proper faith. I want to clarify that this doesn't mean that only beliefs relating to the Abrahamic God are real because that is what constitutes divine call. The call to delve into the transcendent, to discover the mysteries of the universe is this divine call. Through different circumstances such as previous life experience or cultural milieu to which one is born which may steer someone into a particular direction. The RCC teaches that only in Christ is salvation assured (and even then it teaches that no one can be sure of their own salvation) but that those who are not in Christ in the sense that they are Christian may be saved. The Church merely represents the fullness of salvation, but not the finite. God bless.
I think you are thinking or asking the wrong questions. Why do you "want" to believe? Do you think that believing will make it true? If you have been indoctrinated to think that the word "Faith" is a virtue, you are have been mislead when it comes to religious faith. Faith, in the religious sense means belief without logical proof or empirical evidence, and that is not logical nor is it a virtue and it doesn't make something true either. Here is an example of 2 different faith type statements.... 1. I have faith that the sun will rise tomorrow. 2. I have faith that "A God" exists The difference between the two statements is evidence. IN statement one, we have eons of evidence that the sun has risen each and every day. In statement two there is no evidence and thus, belief is held without logical proof or empirical evidence. Some may make the claim that they had a personal experience that they have attributed to their god, and that is evidence of their god, such as praying for something and then thinking the prayer was answered. This is not evidence of a god, it is evidence of a coincidence. I can say this because people with different gods than yours can do the same thing and have approximately the same success rate in getting prayers answered. While personal experience may seem like a good reason or even a rational one, this can only be true of the experience can be shared the same way with everyone. We all see the sun rise each day, but we certainly don't see the same gods every day nor do we see the same god in the same ways, if we did, there wouldn't be a need for various sects of the same religions let alone all the different religions available. The questions you should ask yourself are "what reasons are there to believe in one religion (God) over another"? Are your reasons based on evidence? Are the reasons rational? What is the evidence and can it be tested and repeated?
