Let's look at a parable that Jesus is supposed to have said:
The Parable of the TenantsThe allegory is obvious:
Mark 12:1 He then began to speak to them in parables: "A man planted a vineyard. He put a wall around it, dug a pit for the winepress and built a watchtower. Then he rented the vineyard to some farmers and went away on a journey. 2 At harvest time he sent a servant to the tenants to collect from them some of the fruit of the vineyard. 3 But they seized him, beat him and sent him away empty-handed. 4 Then he sent another servant to them; they struck this man on the head and treated him shamefully. 5 He sent still another, and that one they killed. He sent many others; some of them they beat, others they killed. 6 "He had one left to send, a son, whom he loved. He sent him last of all, saying, 'They will respect my son.' 7 "But the tenants said to one another, 'This is the heir. Come, let's kill him, and the inheritance will be ours.' 8 So they took him and killed him, and threw him out of the vineyard. 9 "What then will the owner of the vineyard do? He will come and kill those tenants and give the vineyard to others.
The owner of the vineyard = God
The vineyard = Israel (as God's Kingdom)
The tenants = the Jews
The servants that get beaten up or killed = the prophets
The son of the owner = Jesus
The others = the Christians (or rather Jewish Christians at the time)
So the story is about the Jews killing Jesus and Jesus promising that God will avenge this by coming soon and killing them ( = the Jews, the unfaithful who have rejected Jesus):
How does this fit into his teaching of love and forgiveness?
(On a side-note: The parable also doesn't reflect well on BibleGod since the owner doesn't seem to be very bright. He keeps sending his servants to the tenants, knowing (and one doesn't even have to be omniscient in this case) that they will get beaten up or killed. I mean ok, one couldn't know this when the first servant was sent and beaten up, but when the third one was killed, one could start to detect a pattern and rethink the strategy of sending lone servants there on a potential suicide mission ... why not send ten of them together? And why send the only son alone too? That's called courting disaster!)
