I am a member of a IFB Church...and i have a question regarding when pastors at the end of the sermon says "to bow your head and close your eyes....and if your are saved could i see your hands". Where did this practice originate from? And why the secrecy about letting a non christian know about your salvation? Is this showing that you are a coward...would you not want the non believer to know? Is the practice rooted in scriptures? Thank you in advance for your response.
