This isn't foreign. This goes back to when we were taken to Ezekiel and other times in the Old Testament. Remember what Jesus said to Peter? (see John 21:17)
Maybe it is to literally feed the hungry body, or perhaps the hungry soul? Maybe it is to help one find the Living Water, or to quench a physical thirst? Perhaps it is to accept the rejected, or cover the vulnerabilities of those we love, rather than expose them? It might be to visit those with physical ailments, but then it might be to stay by the side of those mentally and emotionally enthralled by circumstances? It could look like going to a jail and ministering, or simply ministering to someone captivated by their addictions and decisions. How are we to know?
The answer is the Holy Spirit. We look to the Holy Spirit and respond. The Spirit teaches EVERYTHING we need to know.
