I wondered, as I thought about this passage, what modern-day evangelists were saying to potential converts. Then I remembered who he was talking to--his disciples, insiders, not the crowds, the uninitiated.
He was telling those who were already following him what the Christian way will be like for them. I then wondered about what our current Methodist evangelism material is like. I found this resource: Transforming Evangelism: The Wesleyan Way of Sharing Faith
Here's a quote from the review by Kwasi Kena:
The book looks at John Wesley, in particular, as a great evangelistic practitioner. Wesley's central motive for evangelism was not to recruit new members. Instead, profound gratitude to God and deep compassion for others motivated him. Love for God and neighbor were central. Wesley abhorred cheap love. He challenged people to broaden their thinking of who their neighbors were and to discern what responsibility they had toward their neighbors.
