In the famous Aesop Fable, we read about a fox who unsuccessfully tried to get some grapes, but at last had to give it up, and walked away with his nose in the air, saying: “I am sure they are sour.”
Someone made a second part to this story. Fox did some rehearsal in the night and came on to the scene next day, and jumped with difference and got the grapes from the vine tree, and he began to eat to his full capacity. To his surprise, he found that “yes grapes are really sour.”
Similarly, many have termed John 3:16 as the essence of the Bible which says God sent his only-begotten son to die for our sin as “the Lamb of God who takes away the sin of the world!” (John 1:29). So he came, and died for our sin. This is the first part of the episode.
Second part can be discerned from looking at the world condition after Jesus’ sacrificial death. Sin still rules the lives of many people as it was before the sacrifice. Since sin’s effect started immediately after the original sin was committed, it is inevitable that effect of ransom sacrifice (antidote to sin) should have started immediately after ransom sacrifice is performed.
If this teaching was true, sin would have disappeared from earth!
