Near the end of Luke 2 there is a shift from God’s mercy to the reality that the coming of Messiah also means judgment for some. We see this in Simeon’s prophetic song:
“This child will be rejected by many in Israel, and it will be their undoing. But he will be the greatest joy to many others. Thus, the deepest thoughts of many hearts will be revealed.” 2:34-35 (NLT)
But that is not the end of this dark cloud rising over Israel. John the Baptizer’s ministry ups the ante. He rejoiced in the repentance of many, but was surprised to see others.
“You brood of vipers! Who warned you to flee God’s coming judgment?” 3:7
“Even now the ax of God’s judgment is poised, ready to sever your roots. Yes, every tree that does not produce good fruit will be chopped down and thrown into the fire.” 3:9
“I baptize with water, but someone is coming soon who is greater than I am- so much greater that I am not even worthy to be his slave. He will baptize you with the Holy Spirit and with fire. He is ready to separate the chaff from the grain in his barn but burning the chaff with never-endedin fire.” John used many such warnings as he announced the Good News to the people.” 3:16-18
Jesus’ ministry was not all good news. It was also judgment on Israel. The true Israel was about to be separated from false Israel. It is not about blood line (John said this in 3:8 too). The true Israel is comprised of those Israelites who believe, and believing Gentiles are grafted onto Israel (see Romans 9).
Judgment on unbelieving Jews took place, as prophesied by Jesus (Mt. 24) in 70 AD. The age of Israel was done- the wrath of God for all the murdered prophets and especially the Prophet was poured out on that generation (Mt. 23).
This process continues to this day with regard to all of humanity. Jesus reveals the the deepest thoughts of hearts- who treasures Him and who rejects Him. The former receive the Holy Spirit, and the latter receive fire, an unquenchable flame. Some seem to think this strange- calling Him ‘the Torturing God’ as though wacked out, far right nutjobs made this thing up. But there it is in Scripture- Jesus is worth treasuring, rejoicing in. To despise His glory is an act of cosmic treason. This judgment provides a backdrop for us to more fully understand the glories of His grace. We who believe have been rescued from eternal condemnation.
