It is clear that John the Revelator was "in the Spirit" when he "saw" the immortal Lord Jesus Christ on Patmos Island:

Rev. 1
9I, John, your brother and fellow partaker in the tribulation and kingdom and perseverance which are in Jesus, was on the island called Patmos because of the word of God and the testimony of Jesus.
10I was in the Spirit on the Lord’s day, and I heard behind me a loud voice like the sound of a trumpet,
11saying, “Write in a book what you see, and send it to the seven churches: to Ephesus and to Smyrna and to Pergamum and to Thyatira and to Sardis and to Philadelphia and to Laodicea.”
12Then I turned to see the voice that was speaking with me. And having turned I saw seven golden lampstands;
13and in the middle of the lampstands I saw one like a son of man, clothed in a robe reaching to the feet, and girded across His chest with a golden sash.
14His head and His hair were white like white wool, like snow; and His eyes were like a flame of fire.
15His feet were like burnished bronze, when it has been made to glow in a furnace, and His voice was like the sound of many waters.
16In His right hand He held seven stars, and out of His mouth came a sharp two-edged sword; and His face was like the sun shining in its strength.
17When I saw Him, I fell at His feet like a dead man. And He placed His right hand on me, saying, “Do not be afraid; I am the first and the last,
18and the living One; and I was dead, and behold, I am alive forevermore, and I have the keys of death and of Hades.
19“Therefore write the things which you have seen, and the things which are, and the things which will take place after these things.
20“As for the mystery of the seven stars which you saw in My right hand, and the seven golden lampstands: the seven stars are the angels of the seven churches, and the seven lampstands are the seven churches.

And therefore, that passage does not contradict this one below:

I Tim. 6
13 I charge you in the presence of God, who gives life to all things, and of Christ Jesus, who testified the good confession before Pontius Pilate,
14 that you keep the commandment without stain or reproach until the appearing of our Lord Jesus Christ,
15 which He will bring about at the proper time—He who is the blessed and only Sovereign, the King of kings and Lord of lords,
16 who alone possesses immortality and dwells in unapproachable light, whom no man has seen or can see. To Him be honor and eternal dominion! Amen.

or this one:

I Tim. 1
15It is a trustworthy statement, deserving full acceptance, that Christ Jesus came into the world to save sinners, among whom I am foremost of all.
16Yet for this reason I found mercy, so that in me as the foremost, Jesus Christ might demonstrate His perfect patience as an example for those who would believe in Him for eternal life.
17Now to the King eternal, immortal, invisible, the only God, be honor and glory forever and ever. Amen.

Why?

Because for any saint to "see" Jesus, they would have to have the kind of experience that John the Revelator had on Patmos--they would have to be "in the Spirit" or similar.

And the following passage describes experiences that are similar to the experiences of John apropos "seeing" Jesus:

Acts 9
1Now Saul, still breathing threats and murder against the disciples of the Lord, went to the high priest,
2and asked for letters from him to the synagogues at Damascus, so that if he found any belonging to the Way, both men and women, he might bring them bound to Jerusalem.
3As he was traveling, it happened that he was approaching Damascus, and suddenly a light from heaven flashed around him;
4and he fell to the ground and heard a voice saying to him, “Saul, Saul, why are you persecuting Me?”
5And he said, “Who are You, Lord?” And He said, “I am Jesus whom you are persecuting,
6but get up and enter the city, and it will be told you what you must do.”
7The men who traveled with him stood speechless, hearing the voice but seeing no one.
8Saul got up from the ground, and though his eyes were open, he could see nothing; and leading him by the hand, they brought him into Damascus.
9And he was three days without sight, and neither ate nor drank.
10Now there was a disciple at Damascus named Ananias; and the Lord said to him in a vision, “Ananias.” And he said, “Here I am, Lord.”
11And the Lord said to him, “Get up and go to the street called Straight, and inquire at the house of Judas for a man from Tarsus named Saul, for he is praying,
12and he has seen in a vision a man named Ananias come in and lay his hands on him, so that he might regain his sight.”
13But Ananias answered, “Lord, I have heard from many about this man, how much harm he did to Your saints at Jerusalem;
14and here he has authority from the chief priests to bind all who call on Your name.”
15But the Lord said to him, “Go, for he is a chosen instrument of Mine, to bear My name before the Gentiles and kings and the sons of Israel;
16for I will show him how much he must suffer for My name’s sake.”
17So Ananias departed and entered the house, and after laying his hands on him said, “Brother Saul, the Lord Jesus, who appeared to you on the road by which you were coming, has sent me so that you may regain your sight and be filled with the Holy Spirit.”
18And immediately there fell from his eyes something like scales, and he regained his sight, and he got up and was baptized;
19and he took food and was strengthened.
