There are only two references to this title of the Lord: in Jeremiah 42:5 and in Revelation 1:5; but yet I think it is an important title, worth our study. Jesus is and will always be called the faithful witness, because He is a person of truth and entirely righteous. He will always speak the truth; He cannot lie. Proverbs 14:5 says, “A faithful witness will not lie, but a false witness speaks lies.”
Now when I said that He is a person of truth and entirely righteous, what I am saying is that God’s Spirit in His fullness is in Him. Listen to the following passage in Isaiah 11, which speaks of Him as the Messiah and how the Spirit of the Lord will rest on Him. Notice the different aspects of God’s Spirit, each of which is in Christ the Messiah.
Then a shoot will spring from the stem of Jesse,
And a branch from his roots will bear fruit.
2 And the Spirit of the Lord will rest on Him,
The spirit of wisdom and understanding,
The spirit of counsel and strength,
The spirit of knowledge and the fear of the Lord.
3 And He will delight in the fear of the Lord,
And He will not judge by what His eyes see,
Nor make a decision by what His ears hear;
4 But with righteousness He will judge the poor,
And decide with fairness for the afflicted of the earth;
And He will strike the earth with the rod of His mouth,
And with the breath of His lips He will slay the wicked.
5 Also righteousness will be the belt about His loins,
And faithfulness the belt about His waist.
Now what of His witness? What does He as a witness testify to? There are three passages in John that tell us: John 3:32; 8:14-16; and 18:37. From these passages we clearly see that He is a witness of the truth, which He has seen and heard of God. And the very interesting thing in John 8:14 is that He said that He did not have to go beyond Himself to witness the truth. No, He found the truth in Himself—because He Himself is God and is totally righteous and true. He is the faithful witness.
The First-Born of All Creation and Of the Dead
When it applies to Christ the term first-born indicates that He is the highest in rank. He is the highest in rank over all creation because He is the creator—the creator of all things. And all things were created for Him—to please Him. He is also the firstborn of the dead, which means that He is supreme over all who have died and have been raised. Hence, this title puts away for us all doubt that for eternity He will be supreme over all His glorified ones.
And He is the image of the invisible God, the first-born of all creation. 16 For by Him all things were created, both in the heavens and on earth, visible and invisible, whether thrones or dominions or rulers or authorities — all things have been created by Him and for Him. 17 And He is before all things, and in Him all things hold together. 18 He is also head of the body, the church; and He is the beginning, the first-born from the dead; so that He Himself might come to have first place in everything.

The Alpha and Omega, the First and the Last, the Beginning and the End
The title Alpha and Omega are the first and last letters of the Greek alphabet; hence, since the alphabet contains all known knowledge, this suggests that all knowledge is contained in Him; there is no knowledge outside of His knowledge.
Moreover, the titles “the first and the last,” and “the beginning and the end” are also expressions of His deity and of His eternal existence—that He has existed from eternity past and will exist into eternity future.
“I am the Alpha and the Omega, the first and the last, the beginning and the end.”
