Rick got talking to an older lady who turned out to be Jehovah's Witness. She is very active in it, but didn't really know her Bible very well. She was advocating the idea that since the wages of sin is death, therefore no one will be judged on judgement day based on what they've done in this life, since they have already paid for their sin by dying.
So we shared with her some Scriptures like Romans 2:5-6, where it speaks about people storing up wrath for the day of wrath based on their actions now. She responded "You'll never change my mind!" So we encouraged her to be open-minded to what the Bible says and so she eventually agreed to write down these Scriptures we were mentioning to her to look them up later.
But she didn't have a pen. However, at that moment her teenage granddaughter turned up and said she would write them in her phone. She did this and then while Rick was talking with the grandmother, I started witnessing to the granddaughter who was an active Jehovah's Witness as well.
She had a lot of questions, like "How can there be a Hell if God is loving?", "What about the 140,000?", "What about the paradise Earth?" As I was answering her questions, I could tell she was listening intently.
At one stage, she mentioned how she believes the Holy Spirit is merely God's active force. I said, "Why then does it say in Ephesians 4:30 'Don't grieve the Holy Spirit?'" I asked her, "How can you grieve a force? Only persons can be grieved. That means the Holy Spirit is not a force but a person, one of the persons of the Godhead." She actually came to agree.
I then went on to explain how Jesus said in Matthew 5:48 we must be perfect for our whole life, but we are not and therefore deserve Hell. And simply trying to be perfect isn't good enough.
I went on to explain the gospel, and she was beginning to grasp it - that her witnessing, church going and praying couldn't save her, but only faith in what Jesus has done on the cross could.
I also warned her to not believe the Watchtower organisation, but only the Bible. For I pointed out that even the Watchtower themselves acknowledges that they have made false predictions in the past (like when Jesus would return), and so therefore they are a false prophet and shouldn't be believed. She thought that was a good point.
She said she would seriously think about what she heard and read those passages she wrote in her phone.
Afterwards Rick told me that the grandmother wasn't open at all to hear what Rick was saying, but Rick continued the conversation with the lady long enough so that I could talk thoroughly with her granddaughter.
Please pray for both ladies.
To God be the glory!
