I was rightly convinced decades ago. Reverence for Jesus, the fear of God, (in the book of acts, in the first century) was not at all like Christianity today. The people were not baptized as a beginning of their Christian walk. They were baptized because they were "walking".
They were not baptized because they believed the message of the gospel. They were baptized as a sign and seal that they were living the Gospel.
How does that compare to what you have witnessed?
