Rationality will not give you certainty or increase your eman...you will have some arguments but in the final analysis all reasons can be broken. Sometimes it is better to just say I believe, because I do...build a relationship with Allah, through worship of Him, abstaining from sins and maybe connecting oneself with a shaykh who will teach you ihsan (to worship Allah as though you see Him or to Know that He sees you).
