There is a popular evangelizing method that involves convicting a person of their sin by using the ten commandments. I thought I would share the thoughts I would have had as a Jehovah's Witness:
"Yeah I know the ten commandments, of course we should try to keep them."
"But everyone is imperfect and God understands this, besides, that's the
old law under the Old Covenant, it isn't God's will for me today."
"Yeah, I've lied, what's your point? I've repented from that. I don't do that anymore.
Now I am focused on strengthening my faith and obedience so that I am
ready to endure the end and obey God's direction to survive Armageddon."
"The Great Tribulation... that's what people need to know about.
I have to stay faithful through all of that or all of my work will be for nothing. I'll do anything as long as I get everlasting life in paradise at the end of it. What if I am not faithful enough? I have to make sure I obey the governing body now. I never know if one thing that they ask is the big test, my chance to get on the ark. I can't miss it. What if I miss it? I need to tell these people about Armageddon or they'll be destroyed and their blood will be on my hands."
"This Christian thinks I am so stupid that I don't know John 3:16? I know Jesus died to make up for Adam's sin. Without that I wouldn't have a chance at all. Now I need to prove to God that I am worthy to be in the New System. Then we will all be perfect. I definitely won't sin once I am perfect. Stupid Adam!"
"Yes, Jesus died for me when I was still a sinner. He did this as a gift. I have to show God that I am grateful and will work hard enough for Jesus' death not to be wasted on me."
