Dear Ramkumar ji,
Hari Om. Pranams.
I remember a statement by one great mahatma - 100% faith is same as Self Realisation.
Even if we don't have 100% faith right now but at least if we have correct self-evaluation ("I am not All Knowing" and "I am not All powerful"), added to that if we have ability to observe and analyse all happenings around us in detached manner with a conclusion that "universe is not a chaos but there is a order so there must be a bigger higher intellect behind it and since he clothed me and fed me when I came here as a naked helpless baby, He must be compassionate too". I think with this much knowledge also one can become a devotee. Then he gets special eyes to 'see grace'. Grace is always there but we fail to see it without devotion. Once we are able to recognize grace then we know better than to trust our deluded mind for everything. Grace becomes our intellect as though. Grace makes us put self efforts to gain chitta shuddhi, grace takes us to good Teachers, grace gives us Self Knowledge also. Grace does everything for a devotee. Devotee just has to keep holding on to grace, follow the pointers and strictly obey, whether he understands everything or not.
However, the most beautiful thing is there is no effort in holding on to this grace. Just like we dont need any effort to keep sucking on the candy in our mouth while it melts, there is no effort to keep holding on to Grace/feet of the Lord/Supreme Self/ Guru whatever name you may want to call that grace by. It itself is sweet 'juice'.
By the way, Lord's world is full of so many wonders that there are many ways to get somewhere. One can get to it the way you mentioned also. Who knows by what way Lord might pull us to Him ? and once He pulls us to Him who cares what way we got there?
