Why is the gospel of John so different?
The three synoptic gospels start different than John. Jesus' message of each of the synoptic gospels doesn't start until after an introduction of Jesus' ancestry and John the Baptist's message. After that the gospels will follow Jesus as He interacts with the nation of Israel. Jesus is sent to the nation of Israel. He is talking to and interacting with people who are, for the most part, sinners under the law, therefore, they are sinning. The NT does not start until Jesus dies. Therefore, caution has to be used when applying scriptures to His church.
The gospel of John starts out before the world began introducing Jesus as the Word of God. Then John the Baptist's mission is described briefly. Next, the Word becomes flesh and His purpose is described briefly. Then there is a wedding taking place on the third day which is prophetic. It is also important that Jesus, to honor His earthly parent, pushed His hour ahead. Therefore, John could write of the doctrine after His hour. After the wedding Jesus cleanses the Temple. In chapter 3 John describes how the bride is chosen. His message is for His bride, righteous people not under the law. For the most part John's gospel applies to His church.
Therefore, in general, the main gospel that can be applied to His church is the gospel of John. The other gospels, except where He deals with His disciples and a few other places, does not apply to His church.
Example: Luke 13:2 And Jesus answered and said to them, "Do you suppose that these Galileans were worse sinners than all other Galileans, because they suffered such things? 3 I tell you, no; but unless you repent you will all likewise perish. NKJV
The above message cannot be applied to His bride because His bride is righteous. Jesus was talking to people under to law and still in sin. His bride's sins are forgiven, and her sins are covered by Jesus' blood.
Another example: Matthew 19:17 So He said to him, "Why do you call Me good? No one is good but One, that is, God. But if you want to enter into life, keep the commandments." NKJV
Jesus does not need to tell His bride to keep the commandments to enter life. Why is that?
Romans 4:6 just as David also describes the blessedness of the man to whom God imputes righteousness apart from works: 7 "Blessed are those whose lawless deeds are forgiven, And whose sins are covered; 8 Blessed is the man to whom the Lord shall not impute sin." NKJV
Because the bride's righteousness is imputed to her through her faith, not works. She is ready to enter eternity.
Test: Can the following be applied to His bride?
Mark 8:31 And He began to teach them that the Son of Man must suffer many things, and be rejected by the elders and chief priests and scribes, and be killed, and after three days rise again. 32 He spoke this word openly. Then Peter took Him aside and began to rebuke Him. 33 But when He had turned around and looked at His disciples, He rebuked Peter, saying, "Get behind Me, Satan! For you are not mindful of the things of God, but the things of men." NKJV
People do not rebuke God. Jesus called Peter Satan; he must have blasphemed.
Yes, this can be applied to the church. What Jesus told Peter to do is the same thing as He tells His church to do when they make a mistake (sin). He wants His church to repent and walk in the Spirit (follow Him).
John 2:13 Now the Passover of the Jews was at hand, and Jesus went up to Jerusalem. 14 And He found in the temple those who sold oxen and sheep and doves, and the money changers doing business. 15 When He had made a whip of cords, He drove them all out of the temple, with the sheep and the oxen, and poured out the changers' money and overturned the tables. 16 And He said to those who sold doves, "Take these things away! Do not make My Father's house a house of merchandise!" 17 Then His disciples remembered that it was written, "Zeal for Your house has eaten Me up." NKJV
This definitely applies to His church and this placement is important. First thing after the wedding Jesus cleanses the temple. We are the temple of God. We are His fiancé, to the Jews we are considered His bride. Jesus does not require, it's good if we do, us to prepare His temple for His arrival (repent), He sprinkled His blood over everything and made it clean. After that we need to heed His voice and follow Him with a dustpan. He will clean His temple. He will put items in the dustpan for us to throw out. It is our job to let go of the things that He chooses to throw out. Hopefully, sooner rather than later, we ourselves will toss things out.
Do we have to clean the temple to be saved? No! If we had to clean the temple to be saved, it would be a works-based salvation. The problem arises if we do not want the temple cleaned. In that case we kick Jesus out of the Temple because He cannot leave the temple dirty. He will not leave on His own. Because He will get a clean temple even if He has to kill us to get it, some people will choose to kick Him out. Heaven is only for those who want it. He will not stay where His services are not welcomed.
John 3: 19 And this is the condemnation, that the light has come into the world, and men loved darkness rather than light, because their deeds were evil. 20 For everyone practicing evil hates the light and does not come to the light, lest his deeds should be exposed. 21 But he who does the truth comes to the light, that his deeds may be clearly seen, that they have been done in God." NKJV
Can the above be applied to His bride.
Not verses 19-20 because there is no condemnation for those who believe in Him. There are verses that I could cite, but here's the ultimate reason- because God says so. Under the new covenant anyone that believes in Jesus cannot sin. That is His law under the new covenant. Millions of unsaved people will scream “that's unfair.” His bride says “Praise God and thank you for Jesus. "Which group are you in?
