I realized I never told the end of the story about Danielle...
She did end up calling me back, telling me on the message she left that she had a good reason for not being ready for church that Sunday morning. She asked me to call her back so she could tell me what happened.
I did not feel led by the Lord at that time to call her back (had learned by then to listen to Him instead of doing it "my way"). I was also a little angry with her and felt like she would deceive me more. I realized that I am not her savior or anyone's—Jesus is that.
A few days after the message, she ended up texting me from a random number. In her texts, she told me her "story"—she had been arrested and in jail for something like not paying a ticket (supposedly). That's why she wasn't there Sunday morning.
I guess I felt more deflated after that. I decided not to respond at that time and just kept praying for her and asking the Lord if/when He wanted me to reach back out.
He finally gave me the go-ahead one day on my way into work. And He helped me see what I could still offer her. I didn't feel like she was dependable enough to help her find work, but I did feel like I could offer to continue building a friendship. So I called and left her a message, asking if she wanted to meet for coffee again. Unfortunately, she has never called me back. I am a little sad she hasn't. I still pray for her...
