Let me tell you a couple stories. Some time a go, I invited a friend of mine to join me for a bible study. He came that week to our group. During the study he kept arguing with what we were learning in the scriptures. Afterwards when I dropped him at home, I asked him if we would like to join us next week. I had little hope he would be interested, but he agreed to come again. This continued for several weeks, though his arguments decreased. He was demonstrating a growing conviction of the Spirit. Finally, one day he blurted out to me, "You are getting to me."
Another fellow I was sharing the faith with seemed to react by becoming a heartier sinner. If anything, his life got messier than ever. It was like a great spiritual struggle. Still in his case, he walked out of the battle into a new faith.
Other times I observed a growing interest and excitement over the things of God. Suddenly the person begins to read the scriptures or attend a church. Some exhibit a new openness to talking about God.
How have you noticed people responding to the work of the Spirit in their hearts?
