Life was, in some respects so much simpler then. Yet, in other aspects it was much the same as today. That is, the gospel has never changed. People have changed, but the gospel has not changed. In his second letter to Timothy, Paul gives instructions to Timothy to "preach the word; be ready in season and out of season; reprove, rebuke, and exhort, with complete patience and teaching." (2 Timothy 4:2 ESV)
We learn that the reason for being ready to reprove, rebuke, and exhort with patience and love is that, even in the early church, there were teachers who opposed the gospel of Jesus being preached and taught by Paul and the other apostles. Timothy was warned about one such individual. Listen in and see how we should treat such individuals today - spoiler alert, it comes down to how we are to treat our enemies and persecutors.
