Wombat,
I understand exactly what you are talking about when it comes to religion. The historic truth is; some of the most horrific and atrocious actions have been perpetrated by people in the name of religion. But contemplate a minute: Can we blace God because people do not obey Him. God has had recorded that there is only ONE RELIGION that He is blessing today, Eph 4:3-6. This today is the True Christian Congregation, which is a pillor and support of the truth, 1Tim 3:15. There is a word; syncretism, and by this process chrisendom has become adulterated with false beliefs, jut as was warned about by Bible writers, Acts 20:29,30, Col 2:8, 2Pet 2:1-3.
A very important thing to think about is how God condemns those who say they are doing His will and are lying. Because these ones are claiming to be Christian, and not obeying Bible commands, they cause other people to blaspheme the Name of God, Rom 2:23,24.
One real important reason for problems is the belief in more than ONE GOD. To be a true Christian you must believe only in one God, John 17:3, 1Cor 8:4-6,the God of the Holy Bible, 2Pet 1:20,21,who is the source of life, Ps 36:9, who created the Heavens and the Earth, Isa 45:18, and all the things in them, Rev 4:11.
If you really think about it you realize that if the truth of the Gospel was really being taught, John 17:17, 1Pet 1:25, the world would be getting to be a better place to live in every day, Heb 4:12,13, Eph 4:22-24. The Gospel is God's means for salvation to everyone who will listen, Rom 1:16. God only blesses those who speak the TRUTH and teach the truth, John 4:22,24. That is NOT christendom today!!!
For any of us to be blessed by God and have the opportunity to live through the Great Tribulation, we must separate ourselves from false christendom, and search for that one religion that God favors.
