If God is good (Off course God is good because God like all people and give big chance to those who make sins to come back on the right path)
Then sure God will teach us the good things.
But how do we get these good things? There must be one way and as we do not listen to God, so God sent messengers to teach us the good values and avoid the bad manners.
The process in which God tells his prophet is called Wahy, except Mouses as God spoke to him directly.
We as a human being are very limited in knowledge as every day there is new discovery.
We are the one who bring chaos by not following the good things.
If you start from one point you can not come back unless if there is reference.
Religion is the reference because all religions tell us to do the good things, therefore there is no reason to say that religions are the source of trouble and problems.
At the end if the religion does not make a better person of you, this will be your mistake and it is not the religion mistake.
You have to be open minded and read the full sentence to reach the satisfactory answer.
Religion tells you the purpose of living, can some one who do not have religion tell what is the purpose of living?
Also remember that there is love between animals, shall we just be like animals?
You are the one to decide if this religion suits you or no.
