is being in a religiom important to worship god....???

wow buddy calm down with the dots and question marks. that's a little spammy and unecessary but lets see, No I don't believe in "religion" I believe in a relationship with God. We aren't confined by religion unless we choose to be. You have a personal relationship with God and that is what you are supposed to have. Not the rules that man made up.

Is there a religion without worship God?

It is best for believing in the same God and going to the same church as in universal church even though it may be called by many names and have the same goal. Christianity fits that bill. Christ does not care about one' culture, although there are some things that HE disapproves of such as pologamy, and cutting people's heads off as they still do in some isolated places nor cheating and stealing. In countries where Christianity is a minor belief and the people are new to it, they simpllifiy things but the message is still the same. It is just that the traditions of man have confused things. So we come together to adore and praise God, listen to the exhortation, pray for the sermon and for whatever is imoortant then - such as for the harvest, or for the leaders, etc. sing hymns and psalms between each section, give offerings to the poor, and close. What can be more complicated then that?
