Because John composed his record in a clear and simple style, one might tend to underestimate the depth of this gospel. Since John’s gospel is a “spiritual” gospel (see Authorship and Date), the truths he conveys are profound. The reader must prayerfully and meticulously explore the book, in order to discover the vast richness of the spiritual treasures that the apostle, under the guidance of the Holy Spirit (14:26; 16:13), has lovingly deposited in his gospel.

The chronological reckoning between John’s gospel and the synoptics presents a challenge, especially in relation to the time of the Last Supper (13:2). While the synoptics portray the disciples and the Lord at the Last Supper as eating the Passover meal on Thursday evening (Nisan 14) and Jesus being crucified on Friday, John’s gospel states that the Jews did not enter into the Praetorium “lest they should be defiled, but that they might eat the Passover” (18:28). So, the disciples had eaten the Passover on Thursday evening, but the Jews had not. In fact, John (19:14) states that Jesus’ trial and crucifixion were on the day of Preparation for the Passover and not after the eating of the Passover, so that with the trial and crucifixion on Friday Christ was actually sacrificed at the same time the Passover lambs were being slain (19:14). The question is, “Why did the disciples eat the Passover meal on Thursday?”

The answer lies in a difference among the Jews in the way they reckoned the beginning and ending of days. From Josephus, the Mishna, and other ancient Jewish sources we learn that the Jews in northern Palestine calculated days from sunrise to sunrise. That area included the region of Galilee, where Jesus and all the disciples, except Judas, had grown up. Apparently most, if not all, of the Pharisees used that system of reckoning. But Jews in the southern part, which centered in Jerusalem, calculated days from sunset to sunset. Because all the priests necessarily lived in or near Jerusalem, as did most of the Sadducees, those groups followed the southern scheme.

That variation doubtlessly caused confusion at times, but it also had some practical benefits. During Passover time, for instance, it allowed for the feast to be celebrated legitimately on two adjoining days, thereby permitting the temple sacrifices to be made over a total period of four hours rather than two. That separation of days may also have had the effect of reducing both regional and religious clashes between the two groups.

On that basis the seeming contradictions in the gospel accounts are easily explained. Being Galileans, Jesus and the disciples considered Passover day to have started at sunrise on Thursday and to end at sunrise on Friday. The Jewish leaders who arrested and tried Jesus, being mostly priests and Sadducees, considered Passover day to begin at sunset on Thursday and end at sunset on Friday. By that variation, predetermined by God’s sovereign provision, Jesus could thereby legitimately celebrate the last Passover meal with His disciples and yet still be sacrificed on Passover day.

Once again one can see how God sovereignly and marvelously provides for the precise fulfillment of His redemptive plan. Jesus was anything but a victim of men’s wicked schemes, much less of blind circumstance. Every word He spoke and every action He took were divinely directed and secured. Even the words and actions by others against Him were divinely controlled. See, e.g., 11:49–52; 19:11.
