...and the gift of the Spirit to bring things back to memory. God will be communicating his word to us supernaturally. This will be a big part of small meeting. Along with lots of prayer for needs that can't easily be met the way they used to be when things were good. And there will be answers!
And may I point out, it's funny how some, if not most Christians think in terms of sharing the gospel. Since my gifts do not lean on the evangelism side of things I'm always thinking about already saved people and their well-being. Small groups are going to be about sustaining each other in the salvation we already possess. We'll be 'having church', you know, singing songs, praying, encouraging each other, discussing scripture, but without all the distracting liturgy, and it will be participatory - "When you come together, everyone has a psalm or a teaching, a revelation, a tongue, or an interpretation. All of these must be done to build up the church." 1 Corinthians 14:26.
