My personal religious life

During this past summer I got a job. Since I was out of school, I might as well do something that occupied my time and paid me also. When I got home, I didn't really have too much to do so I picked up the Bible and started reading. I really got into Christianity during this past summer, and I can say I became closer and closer to God. When I came to school, it seemed like I cannot find the time anymore to study/read the Bible and I also don't pray as much anymore due to the fact that my mind is so preoccupied with school. With the addition of the arising questions about Christianity, I feel like I am slipping away from God again like I was before this past Summer. I wonder if God looks down and feels sympathetic in a way, knowing that I do not hate him or go against him, it's just that I don't feel like I have enough time to devote myself to him right now. However, there's this other aspect that I get sometimes from religions class that he might be the type of god that would send you straight to Hell if you just stray an inch from the path of his way. So I am sort of conflicted, or maybe that I must realize that being a true Christian is staying on the path and devoting yourself to God as much as possible with no excuses because after all, God made me, so I should be responsible for giving something back. But what if I am giving back to him without even knowing it? Ultimately I think that being a true Christian is really, loving other people, being selfless and knowing that God is there on your side all the time.
