I'll reiterate, all religions are not bad, they do have many good points, they do serve a community, but in amongst the good, bad is also to be found (but largely ignored). Collectively and individually, churches make convenient tax shelters which can be easily abused, just one example.
I agree with you on all of this!!! Christians aren't suppose to turn a blind eye to the kinds of sins within church leadership that would disqualify leaders from being leaders. This instruction by Paul shows that we need to carefully evaluate the conduct of leaders before imitating their faith: Remember those who led you, who spoke the word of God to you; and considering the result of their way of life, imitate their faith. Hebrews 13:7
You say that you do not know God and that you do not know if there is a God. How can you be so sure that what you don't know isn't knowable? I know some things about God based on many differing types of evidence that support this knowledge. Do you have evidence to support your not knowing?
There is no proof, other than the only proof is nature is so marvelously constructed. But that doesn't prove the bible or prophesy. Nature is nigh on perfect but the bible is a shambles, hickery pokery disjointed, contradictory, vague, argumentative, hostile, black and white right or wrong dogmatic, full of vengenance and violence, pitting families against each other in the name of God, I could go on, no need to, you get the gist. That's why christianity is a disaster, because it is a disaster.
The Bible is not in shambles. The Bible explains that because of sin, people's lives are in shambles. God chose to communicate with people and leave a record for future generations to be able to seek God and find God through what has been written from God. The Bible stands apart from all other books AND all other sacred writings of other religions in a number of ways. Below I have laid out just one way in which the Bible shows that it contains direct revelation from God unlike any other religion: Many of the miraculous events recorded in the Bible were written at the same time the events happened and were witnessed by either the entire nation of Israel or by a large number of people. Other religions will often have one or two people who claim to have a revelation from a deity and then they gain a following of people. No other religion, to my knowledge, has recorded as historical events, in the generation they were written, to that generation, large numbers of people encountering physical manifestations of God or miracles This is significant because the events were verified by that generation. For example, with the Exodus, you have an entire nation witness the physical manifestation of God appearing as a cloud by day and a pillar of fire by night to separate the Egyptians from the Israelites until the Israelites could cross the Red Sea. You also have the entire nation walk through the Red Sea because God made a miraculous path for them. The Egyptians who pursued them did not receive protection from God in the Red Sea and drowned. This is very significant because these events were recorded in the same generation and for the generation that experienced this. If those events had not actually happened, then the yearly Passover celebration which also began with that same generation for remembering the Exodus could not have begun as it did which each parent telling their kids that Passover was a day to celebrate the miraculous deliverance of THEMSELVES from Egypt. This has been handed down from generation to generation beginning with those who actually experienced those miraculous events. No other religion has such a strong witness of it's entire nation to the manifestations of God Himself to ALL of them or the numerous miracles that also happened then. 3 Then Moses said to the people, “Commemorate this day, the day you came out of Egypt, out of the land of slavery, because the Lord brought you out of it with a mighty hand. Eat nothing containing yeast.4 Today, in the month of Aviv, you are leaving.5 When the Lord brings you into the land of the Canaanites, Hittites, Amorites, Hivites and Jebusites—the land he swore to your ancestors to give you, a land flowing with milk and honey—you are to observe this ceremony in this month:6 For seven days eat bread made without yeast and on the seventh day hold a festival to the Lord.7 Eat unleavened bread during those seven days; nothing with yeast in it is to be seen among you, nor shall any yeast be seen anywhere within your borders.8 On that day tell your son, ‘I do this because of what the Lord did for me when I came out of Egypt.’9 This observance will be for you like a sign on your hand and a reminder on your forehead that this law of the Lord is to be on your lips. For the Lord brought you out of Egypt with his mighty hand.10 You must keep this ordinance at the appointed time year after year. Exodus 13:3-10
