I returned from Katoomba Christian Convention's Next Gen conference a couple of days ago. At that conference, my training group looked at Malachi 4:1-6 and learned how to understand it, through Christ, as New Testament believers. This is an application of the task of Biblical Theology - understanding the whole bible as one consistent story, centred on Christ, especially his death & resurrection. Here's my notes for a biblical-theological reading of Mal 4:1-6 (Hebrew 3:19-24). Summary: Jesus brings in the Day of the Lord, in his death, and his resurrection, and his return; If we trust Christ, we don't have to fear judgement on that day, but can look forward to being vindicated; Until that day comes, we need to live Christ-like lives, patiently enduring mockery and persecution, and waiting to be vindicated when we share in Christ's resurrection. Detailed notes: John the Baptist is the Elijah who precedes the Day of the Lord. The angel tells Zechariah so (Luke 1:17)....
