1) Do you think that God interferes in your life or do you see God as an observer only?
god controls everyone, although he may not control everyone in the same way
on a broad scale, god controls everyone through rememberence, knowledge and forgetfulness.
BG 15.15: I am seated in everyone's heart, and from Me come remembrance, knowledge and forgetfulness. By all the Vedas, I am to be known. Indeed, I am the compiler of Vedānta, and I am the knower of the Vedas.
in this way he is directing everyone's movements
BG 18.61: The Supreme Lord is situated in everyone's heart, O Arjuna, and is directing the wanderings of all living entities, who are seated as on a machine, made of the material energy.
thus all living entities experience the results of their desires, with god acting as a neutral facilitator (although being material desires, the results are predictable)
BG 13.22: The living entity in material nature thus follows the ways of life, enjoying the three modes of nature. This is due to his association with that material nature. Thus he meets with good and evil among various species.
for one who is a sincere worshiper of god however, there is a slightly different emphasis
BG 10.10: To those who are constantly devoted to serving Me with love, I give the understanding by which they can come to Me.
BG 10.11: To show them special mercy, I, dwelling in their hearts, destroy with the shining lamp of knowledge the darkness born of ignorance.
in other words for the sincere theist, god inspires them in the heart (through knowledge, rememberence and forgetfulness, the same as any one else) on the correct path to get relief from material entanglement and attain spiritual knowledge
this reciprocation between god and the living entity continues with greater intensity until it develops to the point of direct perception
2) If YES to #1 what is an example where God did something?
CC Ādi 14.1: Things that are very difficult to do become easy to execute if one somehow or other simply remembers Lord Caitanya Mahāprabhu. But if one does not remember Him, even easy things become very difficult. To this Lord Caitanya Mahāprabhu I offer my respectful obeisances.
basically they follow along that path
3) Would you still worship God if he did nothing for you in life?
if one has no experience of god's reciprocation, then adhering to spiritual life simply becomes dry, or even worse, another aspect of materialistic culture
4) Would you still worship God if he did nothing for you in life and you were not granted an afterlife? That is to say, you simply ended.
before service to god (which is abhedya or practical application - the means to the goal) there is knowledge of god (sambhanda or theoretical knowledge) - after all it would very difficult to render service to someone that one knows nothing about - so naturally if there is some fault in theory (as in concluding that after death one simply ceases to exist) one would expect it to curtail the service
I suppose I was wondering about the motivation for the continual supplication?
here is an excerpt
When Lord Caitanya Mahäprabhu came to know of this, He punished Mukunda, forbidding him to see Him again. Although Caitanya Mahäprabhu was soft like a flower, He was also strict like a thunderbolt, and everyone was afraid to allow Mukunda to come again into the presence of Çré Caitanya Mahäprabhu. Mukunda, therefore, being very sorry, asked his friends whether he would one day be allowed to see Lord Caitanya Mahäprabhu. When the devotees brought this inquiry to Lord Caitanya, the Lord replied, “Mukunda will get permission to see Me after many millions of years.” When they gave this information to Mukunda, he danced with jubilation, and when Lord Caitanya Mahäprabhu heard that Mukunda was so patiently waiting to meet Him after millions of years, He immediately asked him to return.
basically, the ideal devotee of god is so surrendered to god that name, fame adoration, wealth etc and even liberation itself appear like figs before the performance of service - the result of this is that god cannot help but similarly reciprocate with such a rare soul
BG 6.30: For one who sees Me everywhere and sees everything in Me, I am never lost, nor is he ever lost to Me.
