Main teachings of the Gospel of John
The Gospel of John seems to stand out from the rest of the other Gospels due to its attempt to explain the deity of Christ. It documents the teachings of The Lord with greater depth. Even though he may have mentioned some of the Miracles Christ had done to prove His Godly powers, his major focus was to show the world the omniscient side of Him.
The Gospel of John can be divided into two major parts. Chapters 1-12 cover the details which describe the divine nature of Christ, whilst chapter 13-21 are dedicated to the final hours beginning from the Last Supper to the Ascension of Christ.
1. It teaches us about the divine nature of Christ
There are four ways that St. John describes the divinity of Christ in his Gospel. 1. He is everlasting. 2. He is equal to God The Father. 3. He did miracles. 4. He is the Source of Life.
St. John thrives to reveal the divine nature of The Lord by starting to explain that the time of which Christ came in the flesh is not the beginning of His Consciousness. He does not struggle to reach the heavens by beginning from the land of Bethlehem but rather begins our journey from the heavens to Bethlehem. Many find it difficult to understand the divinity of Christ because they begin their search from the time of Bethlehem. However, Bethlehem is where The Lord declared His great love, not where His existence began. The One whom existed as God before the time of Bethlehem became fully Man without changing His divinity. St. John describes the everlasting existence of Christ with God The Father (John 1:1). He explains that Christ is the source of creation and the reason of the existence of all (John 1:3). Even though St. John the Baptist was conceived 6 months before Christ, he has also testified that Lord Jesus Christ lived before him (John 1:30). It is also written that The Lord have said to the Jews that 'before Abraham was born, I Am" (John 8:58). There is 2000 years gap between the time of Abraham and the birth of Christ. When The Lord said He lived before the time of Abraham He was only 30 years old. But He existed before Abraham in His divinity.
St. John reveals the divine nature of Christ by explaining that He lived with God The Father equally before the beginning of time. "In the beginning was the Word, and the Word was with God, and the Word was God" (John 1:1). The Son of God Jesus Christ lived eternally with God The Father and has a special union with Him. Christ did not live with The Father on the sidelines but as God Himself. Christ has also said " I and The Father are One" (John 10:30). God The Father and God The Son have the same existence. Christ is also The absolute Judge (5:19-29).
St. John also revealed the divinity of Christ by writing about the miracles He had done. He wrote about the first miracle Christ had done as He began His service (John 2:1-11). The Lord showed His Glory to His disciples during this miraculous time, which in return made them believe in Him. Another way St. John revealed the divine nature of Christ by explaining that He is The Source of Life, Truth and Light (John 1:4). These things are attributes of God. We are blessed by putting our faith in Christ because He is God. Otherwise, according to the words of Jeremiah we would have all been cursed instead - "Cursed is the one who trusts in man, who draws strength from mere flesh and whose heart turns away from the Lord" (Jeremiah 17:5). It’s also written in the book of 'Haimanote Abew' that no one should believe in Christ with the understanding that He is anything but God, in order not to lose the everlasting life given. For no man can save the world. In the book 'zeablidos' 42:5, it says "The death of a mere man and the baptism in the name of a mere man will not bring any glory, but we will surely find glory by the death of Christ".
May He provide virtue unto us abundantly!
