“Jude reminds us of God’s saving work in Christ that echoes across all of human history. Jude startlingly remarks in verse 5 that it was Jesus who brought God’s people out of Egypt—centuries before the incarnation! Whatever Jude meant to convey here, at the least he is reminding us that Christ’s saving work is not an isolated and disconnected historical event. Rather, Christ’s work of redemption is the climax to all of God’s mighty deeds on behalf of his people.”
