Wow, I LOVE this thread!
I have soooo many stories of Him doing incredible things like the ones Kim has mentioned, and others in this thread.
My favorite is:
A Chinese friend in a Bible study, I'll call her Ellie, was struggling so much with 'if God was really real or not'. The Bible study was for women who most of them had never read the Bible before, and we did inductive Bible study with them."
I had told a dear believing friend of mine about Ellie and we had been praying for her to know the Lord. She had never met Ellie.
Well, this dear friend of mine sensed a prompting to just get up from her quiet time with the Lord one morning and go to the park. It was an urgent sensing, like, now, just go. So, she went. She walked into the park and noticed a person pretty far away wearing a jacket with a hood, couldn't see anything else about them, but had a heavy burden for them that God wanted them to know His peace. She started to walk towards the person and they were walking AWAY, so she had to almost run after them, from across like a field. She caught up to the person, and told her that she knew it might be a little strange, but that she just wanted her to know that God wanted her to know His hope. The girl was Chinese. She was so overwhelmed by this kindness and started to tell my friend that she had been in a Bible study, describing it a bit, and shared that was having a hard time believing that God was real!!!! And after a bit of conversation, it was pretty obvious what had happened and my friend was like...wait are you Ellie!???
It WAS HER!!!
This soooo moved Ellie and when she came to Bible study later that day and told the story, I just cried my eyes out. God was sooo kind and AMAZING! And guess who gave her life to the Lord?? AND HER HUSBAND did too!!! And they were both baptized and took their faith back to China and were a part of a house church.
So, I think we know it's God when there is fruit. God is glorified, and the one who we are in awe of, and His Kingdom is added to and Kingship recognized.
It reminds me a bit of Matthew 12:26-28 (not that this about casting out devils, but I think it applies)
If Satan drives out Satan, he is divided against himself. How then can his kingdom stand?
And if I drive out demons by Beelzebul, by whom do your sons drive them out? So then, they will be your judges. But if I drive out demons by the Spirit of God, then the kingdom of God has come upon you.
