The Church and the Bible

it is actually very hard to understand the Bible using the context of the world today. there are a lot of contradictions and confusions that people, especially the youth, are experiencing, and unfortunately, the Church isn't much of a big help. i mean, there are a lot of priests who're ineffective when they are sharing the Word of God, especially in their homilies, therefore the people are having a hard time understanding AND applying the teachings of Christ. they don't actually give a simple example of how we could actually imitate Christ's way, and most of the time, they just keep droning on and on about their own experiences(or other people's) on some things, which is actually very far from the day's Bible scripture. sometimes its even worse--they just read a page long summary of something and expect the crowd to understand what they've said. i'm not blaming all the priests existing in the world, but i just hope that the Church will really monitor their 'messengers of God's word' in such a way that those 'messengers' would bring the people closer to God.
i'm not only frustrated with the priests, but also with the Bible itself. i'm not really challenging God's supremacy or anything, but frankly, the things written in the Bible seems a bit illogical and impractical in our world today. for example: its really stupid of you if you give everything that you have to your neighbors. i'm not saying that its not good to share, but what if those people you call neighbors take advantage of your kindness? you still give them everything you have, believing that there will be a much, much better reward in the end anyway even if you're now just living in scraps because you actually gave your all to everyone? and there's also the irony in the Bible saying that we should be humble and consider ourselves 'unworthy' so that in the end we will be the ones who're on the top, but we should also be proud of ourselves as God's children, and we should always value ourselves, our possessions, talents, capabilities, etc.... and all those things. so which should we follow?? the former or the latter? and don't you think it is also a bit selfish of us if we think of how we could actually be at the top, higher than everybody else? how we always strive to be higher than those people who're unfaithful to God?
and what's with those mortal sins? anger, pride, lust, envy, gluttony, covetousness, sloth..... does this mean that if we ever get lazy, we're already comitting a sin? that it is wrong to compare ourselves to other people?
so my real questions are these: what is God's true message to us as His children? and how can we be worthy of this title?
