This isn’t envy; rather, it highlights the overwhelming generosity of God's nature, which can leave us bewildered and provoke our murmuring. David articulates the struggles faced by sinners lured by worldly success (Psalms 72:3), as does Jeremiah in his lament over the prosperity of the wicked, saying, “Why is the way of the wicked prosperous? Thou hast planted them, and they have taken root” (Jer. 12:1-2). This mindset is typical of frail and troubled humanity, grappling with the apparent prosperity of those known for their vices. Thus, in the parable, the Lord addresses the Pharisees, saying, “So you, like this son, may consider yourselves righteous before the Father; however, I urge you, who see yourselves as pure, not to grumble because we celebrate the redemption of a sinner, as he is also a son.” The parable encourages the Pharisees not to be troubled by the acceptance of those who have turned from sin, despite their own adherence to God's commandments. It is understandable to feel discomfort when sinners are embraced, for the generosity of God is immensely profound, leading to feelings of resentment. In everyday life, we often find ourselves thinking of how our good deeds go unappreciated, saying, “Everyone judges me for my kindness.” Yet, in reality, it may be that no one criticized us; we simply magnify the nature of our generosity in our minds.
Upon learning of the circumstances, he was reluctant to join in the communal celebration. However, the loving Father came out, called him, and revealed that the cause for joy was the revival of what was lost—knowledge he lacked. The son was tempted to accuse the Father for not granting him a goat while the extravagant feast was made for the wayward child. What is indicated by the reference to the “kid of goats”? We can gather from the teaching that goats are often associated with the left side and denoted as sinners (Matthew 25:33, 41). The faithful son expresses to the Father that despite his labor and the trials he faced, he feels neglected, as he has never been given even a goat—a representation of those who have wronged him—just to enjoy a moment of happiness. For instance, Ahab acted against Elijah, yet the Lord did not swiftly bring judgment upon him to ease Elijah's heart along with his fellow prophets. Hence, Elijah lamented, “They have destroyed Thy altars and killed Thy prophets” (3 Kings 19:14). In David's case, Saul represented those who slandered him and whom the Lord permitted as a test, but did not eliminate despite David's request for justice, as he cried out, “How long, O Lord, shall the wicked, how long shall the wicked triumph?” (Ps. 93:3). Similarly, the son illustrated in the Gospel argues, “You have honored no one who has toiled, nor have you punished any of my mockers, and yet you welcome back the wayward one without any effort.” The essential lesson of this parable, directed at the Pharisees who opposed the Lord for welcoming sinners, is to urge us against rejecting those who have erred and to refrain from grumbling over God's acceptance of them, regardless of our own righteousness. The younger son symbolizes the publicans and harlots, while the elder son represents the Pharisees and scribes, who believe themselves to be righteous. It’s as if God is saying, “You may indeed be just, having kept all commandments, but should you not also welcome those who forsake their wrongdoings?” The Lord uses this parable to caution those who murmur. It is noted that some interpret the elder son as the angels and the younger as humankind, once rebellious and defiant of their Creator's will. Others see the elder as representative of the Israelites and the younger as the Gentiles. However, the understanding that fits best is that the elder son embodies the righteous and the younger son embodies the sinners and those who repent. The entirety of this parable serves to convey to the Pharisees that despite their perceived righteousness, they should not begrudge the redemption of sinners. Let no one be troubled by God’s plans, but strive for patience even when it appears that sinners are being honored and restored. Remember, you may perceive someone as a sinner, but they may have repented and thus be accepted by God. Furthermore, it is quite possible they possess hidden virtues that lead to their favor in God's sight.
