Stand for pure worship,
I don't question your sincerity but may I point out to you the question that decides who is christian and who isn't is the belief about Jesus Christ. Some say Jesus is a good man some say just an historical figure christians say he is the son of God. There is the biblical evidence of who Jesus is as well as the developement of the doctrine through the ecumenical councils. The doctrine of the trinity should be studied with the aid of history because christian doctrine is developed as explained by John Henry Newman in his essay 'An essay on the developement of christian doctrine'.
At church we say the Apostolic and the Nicean creed which divides christianity from non christian religions. Muslims and the witness religion believe in Jesus too but are not a christian religion because they both don't believe Jesus is the Son of God.
