We are, as others have said here, a product of our culture and our learned traditions. Unfortunately, these traditions sometimes have a tendency to "trump" the gospel. We are so blinded by our own way of seeing and doing things, that we cannot understand other culture's response to the gospel. Many instances in Scripture of people sincerely coming to Christ would not pass the test in our own churches (didn't say the ABC's of salvation, no one drew the bridge diagram for them, they didn't say the words we expect to hear, they didn't "walk the aisle", etc.). We have to be so absorbed into the truth of Jesus and the truth of the gospel that these cultural issues are set aside.
I spent many years ministering and connecting with an elderly man in our city who came to Christ in our church. Paul's background was an incredible search for God from his childhood, but he could not read until he was saved and began "listening" to the gospel on tape or in church and trying to follow along. Neither could Paul articulate his deep passion for God... He didn't ever use "church" lingo... he would say "when I got God" or when "God came to me", etc. I did not doubt his salvation, but had to struggle with his cultural background and how he articulated his faith.
