I wrote a post recently about the Pope talking about a 'one world religion' coming. To my concern there shouldn’t be any religion whatsoever. But I do believe that preaching the Gospel would be ideal. That is, so long as whomever would be preaching it would not preach it as a riddle and/or invent things to scare people into having more faith. That's being done now by some preachers or by someone else trying to make you believe that they know what they are talking about. Actually they don’t have a clue or they do not believe in what they are saying.
I would say to save you from the wrath of God all you have to do is believe in Him (the Creator of all things that are not man made) and His Son, Jesus who was tortured and crucified and died on the cross that whosoever would believe in him shall have eternal life. Also live according to God's 10 Commandments that were given to Moses. Live by them. Faith in God and his Son Jesus and living according to the 10 Commandments, a person cannot go wrong. As for confessing your sins, you don’t have to go to another human to confess your sins because if God can hear your prayers then He can hear you acknowledging your sins to Him. If anyone sees you as talking to yourself (actually to God) they will think that there is something wrong with you. But they don’t know that you don’t want to face the Wrath of God when the time comes for you to be judged.
