In response to the first post (#1), it is an important question as to which church is the best to follow (to join). The same question can be expanded to say “Which faith, which religion is the best or better”.
I do not want to distract the questioner into more trouble. But it is a natural consequence of the basic question. There is no harm in exploring the other faiths because God is the God of all creation, all people on the earth. He revealed himself to every nation.
Now, I come to the point. Man did not create God. God created mankind. And revealed Himself to mankind through His agencies (angels). God talks to the men. He reveals Himself to them, to his messengers and prophets.
God used to talk to the mankind and He still talks. He has not become dumb or deaf. Please see in your scriptures that God spoke to Abraham and Moses. He even spoke to the mother of Moses and to the mother of Jesus (Mary).
The last two mentioned ladies were not any prophets. They were common good pious persons. And God spoke to them and gave them some guidance and good news. It was so because of their prayer to God. They prayed to God and God spoke to them. (See detail in the Quran)
So in order to find out any truth, the best thing is to be gentle, unbiased, doing good deeds and having love for all and hatred for none. Then if any one such person will earnestly pray to God and ask for Guidance,i am sure the One God will speak to that person by some manner (dream, vision etc)
That is the best way to find out the truth. One should pray to God (To his/her God) according to own belief as a Jew or a christian or a Muslim. God will reply. I may, in the end post /paste one verse of the Quran on this subject which is quite relevant. Please see:
[2:186] And when My servants ask thee about Me, say ‘I am near. I answer the prayer of the supplicant when he (calls) prays to Me. So they should hearken to Me and believe in Me, that they may follow the right way.’
