John 21:25. And there are also many other things which Jesus did, the which, if they should be written every one, I suppose that even the world itself could not contain the books that should be written. Amen.
It is important to always keep in mind the purpose each of the gospel writers had in presenting Jesus. Matthew presented Christ to the Jews as Messiah, and includes Kingdom prophecy; Mark presented Him as the servant of God, recording more of His miracles than any other gospel; Luke presented Jesus as the perfect Son of Man, and records factually His life on earth; John wrote Jesus as the Son of God, Savior of mankind.
John was selective in what he recorded, because his focus was to encourage faith and belief in the redeeming power of Jesus Christ. Each writer wrote in his own voice, directed by the Holy Spirit. There are no contradictions among the four gospels, no matter how hard some try to create them.
I have two books that I treasure. One is The Harmony of the Gospels by A.T. Robertson. The other is my chronological Bible that helps align all the people and events recorded in God’s word in a chronological way. Another good tool is a chart you can find online at blueletterbible.org, under “study”–or just type “harmony of the gospels chart” in the search option. You get a four-column side by side list of every event, person, miracle, etc. including the references where they occur in each gospel in which they are discussed.
I want to encourage you, if you have never done so, to make time to read the entire Gospel of John in one sitting. One chapter flows into the next. The original manuscripts did not have chapter/verse designations. That tool was created by translators to help us locate more easily the texts being taught, studied, or preached.
And now I’m going to finish by leaving you with this wonderful old song, The Love of God.
