Matthew 20:1-16
There are undeniable difficulties in the parable contained in these verses. The key to the right explanation of them must be sought in the passage which concludes the last chapter. There we find the apostle Peter asking our Lord a remarkable question: “We have forsaken all and followed thee! What shall we have therefore?” There we find Jesus giving a remarkable answer. He makes a special promise to Peter and His fellow disciples: they should one day sit on twelve thrones, judging the twelve tribes of Israel. He makes a general promise to all who suffer loss for His sake: they “should receive a hundred fold and inherit everlasting life.”
Now we must bear in mind that Peter was a Jew, and like most Jews he had probably been brought up in much ignorance as to God’s purposes respecting the salvation of the Gentiles. In fact we know from the Acts that it required a vision from heaven to take that ignorance away (Acts 10:28). Furthermore, we must bear in mind that Peter and his fellow-disciples were weak in faith and knowledge. They were probably apt to attach a great importance to their own sacrifices for Christ’s sake, and inclined to self-righteousness and self conceit. Both these points our Lord knew well. He therefore speaks this parable for the special benefit of Peter and his companions. He read their hearts. He saw what spiritual medicine those hearts required, and supplied it without delay. In a word, he checked their rising pride, and taught them humility.
