"The Christian Life"

I'm a Christian... at least I consider myself as one. But the big thick question is 'am I a good Christian?'... First of all, who and what exactly is a good Christian? If I had to describe a good Christian, it would go something like this: he/she is a person after God's heart, he/she believes in God and His existence, prays and reads the Bible everyday, and worship in His (God) name. Now back to the question, I guess I can consider myself somewhat of a good Christian. I believe in God Almighty and His existence, and I pray and read my Bible "occasionally"....now this is something I'm not proud of. Sometimes I set up a goal for myself concerning my faith in God [and also Bible reading and prayer], but at some point I tend to fall off of that train of determination. I know it's all the work of the devil, but I've been praying to God to give me the self-discipline to fight this battle. I want to get to know my Lord more often than I do right now.
