Great explanation ^^ Plus + As stated above the older son is Jews who thinks that they are saved. Younger son is the pagans who doesn't know Father. When Christ came Both Sons were lost apolumi death in Greek Jn 3:16 death, Jews & Pagans = All humanity is LOST in Sin. Jews rejected Christ, but younger son repented & received the Gospel... So Christ came to Save All Sinners both Jews & Pagan = us ^^
