More than one hundred years ago, in 1895, H. G. Wells classic story “The Time Machine” was first published in book form. Ten years later, in 1905, Albert Einstein published his special theory of relativity that is based on the constant speed of light and the fact that speed is not absolute.  This theory may be illustrated in a simple way.  Let us assume that you are driving an automobile moving in one direction at a certain speed, and another automobile in the next lane is also moving in the same direction at the same speed, then this will be the apparent result.  Although both vehicles are in constant motion but both will appear to be motionless relative to one another.  If you reduce the speed of your automobile you will feel that you are going backwards from the other vehicle when in fact you are still moving forward.             

In simple and plain language Einstein’s special theory of relativity means that if we travel in a spaceship at the speed of light, which is 186,000 miles per second or 300,000 kilometers per second, then time would stand still.  We can choose either to go back into the past by slowing down or go forward into the future by going faster.  This is only a theory that is hard to prove because no ordinary human has ever done that. 

The Holy Bible tells us that the One True God who is the Creator of the Universe is Eternal.  He is in complete control of time and space.  He alone can go back into history and He can also go forward into the future.  To us it is impossible but to Him everything is possible.

When God appeared to Moses at the Burning Bush He revealed His Sacred Name to him.

“Then Moses said to God, "Indeed, when I come to the children of Israel and say to them, 'The God of your fathers has sent me to you,' and they say to me, 'What is His name?' what shall I say to them?"  And God said to Moses, "I AM WHO I AM." And He said, "Thus you shall say to the children of Israel, 'I AM has sent me to you.' "  Moreover God said to Moses, "Thus you shall say to the children of Israel: 'The Lord God of your fathers, the God of Abraham, the God of Isaac, and the God of Jacob, has sent me to you. This is My name forever, and this is My memorial to all generations.' (Ex. 3:13-15)

The One True God’s name “I AM WHO I AM” is pronounced “YAHWEH” in Hebrew.   It means “I exist all the time”.  Some believers call Him the ETERNAL.  The name “I AM” in Hebrew is “YAH”.  In the King James Bible “YAH” is the name of God (Psm. 68:4; Isa. 12:2; 38:11).  When we say “HalleluYah” we are praising the name of God whose name is YAH. 

The name of God YAH that means I AM is the first part of the name of YAH-SHUA – the Hebrew name of JESUS.  The second part of the name of Jesus – SHUA in Hebrew means Savior.  YAHSHUA is the redemptive name of God (Mt. 1:21; Acts 4:12; 10:43; 2:28).   

Let us look into another event concerning the name of YAH.  Here Jesus was talking with the Jews in His time.

“Your father Abraham rejoiced to see My day, and he saw it and was glad."  Then the Jews said to Him, "You are not yet fifty years old, and have You seen Abraham?"  Jesus said to them, "Most assuredly, I say to you, before Abraham was, I AM."  Then they took up stones to throw at Him; but Jesus hid Himself and went out of the temple, going through the midst of them, and so passed by.” (Jn. 8:56-59)

The Jews stoned Jesus because He said that His name is I AM.  From their viewpoint Jesus had blasphemed God.  Here Jesus asserted that He had existed before the time of Abraham.  How can this be possible except that Jesus is truly God and He is the Eternal. 

The apostle John wrote the book of Revelation that gives the future events of the world.  Here is what he wrote:

“Behold, He is coming with clouds, and every eye will see Him, even they who pierced Him. And all the tribes of the earth will mourn because of Him. Even so, Amen.  "I am the Alpha and the Omega, the Beginning and the End," says the Lord, "who is and who was and who is to come, the Almighty." (Rev. 1:7-8) 

Here you can read what the Lord Jesus Christ said about Himself.  "I am the Alpha and the Omega, the Beginning and the End," says the Lord, "who is and who was and who is to come, the Almighty."  Jesus Christ exists in the past, the present and also the future.  He controls time and eternity.

"Jesus Christ is the same yesterday, today, and forever." (Heb. 13:8)

Someone has said, "The only thing that is permanent, is change." We are all aware of how time changes things in the world that we live. On September 11, 2001, in a matter of a few seconds a super jetliner that was hijacked by radical Muslim terrorists crashed into the World Trade Center in New York City and many things have changed since then.  Things are no longer the same in New York City, in America, and indeed, in the world.  As we look back into the past don’t we all wish that the terrorist attack on America had never happened and we could have prevented it from happening?  Many people who have put all their life savings in the Enron stocks wished they had sold them before the company’s sudden crash.  What about our own lives?  We must have wished that we could have changed the situation in such a way that we would not have to experience tragedies, failures and disappointments.  All of us can easily recall the changes that have taken place in our lives during the past year. And, we are certainly aware that the coming year will bring more changes, although we have no way of knowing whether those changes will be for the better or for worse.

In a world in which we are confronted with constant change, it is encouraging to know that there is an unchanging reality that will never change. "Jesus Christ is the same yesterday, today, and forever." While it is true that the Lord Jesus Christ, the Son of God, did experience change when He became flesh and dwelt among us, it is equally true that there was no change as to His essential eternal attributes. According to His own words, He is always one with God the Father. John 10:30 "I and the Father are one." Time and space will allow us to consider only some of His unchanging attributes.

The One True God said: "For I am the LORD, I do not change; Therefore you are not consumed, O sons of Jacob.” (Mal 3:6)   Since our Lord Jesus Christ is God manifested in the flesh He also does not change.  "Jesus Christ is the same yesterday, today, and forever."

Our Lord Jesus Christ’s absolute holiness is unchanging. "For we do not have a High Priest who cannot sympathize with our weaknesses, but was in all points tempted as we are, yet without sin." (Hebrews 4:15)  Christ was born without sin and lived His entire earthly life without sin. Pilate gave testimony to the complete innocence of the Son of God: "Then Pilate said to the chief priests and the crowd, "I find no guilt in this Man." (Luke 23:4)   His holy and sinless life enabled Him to save us from our sins.  “For He (God) made Him (Jesus Christ) who knew no sin to be sin for us, that we might become the righteousness of God in Him.” (2 Cor. 5:21)  In His holiness, Jesus Christ is the same yesterday, today and forever. That unchanging holiness qualifies Him to be the only true Redeemer.

Our Lord Jesus Christ’s faithfulness is unchanging.  His followers can be confident that He is the same, yesterday, today and forever. This means that they can always depend upon Him.   He is not one thing one day, and another thing the next day.

 Let your conduct be without covetousness; be content with such things as you have. For He Himself has said, "I will never leave you nor forsake you." So we may boldly say: "The Lord is my helper; I will not fear. What can man do to me?" Remember those who rule over you, who have spoken the word of God to you, whose faith follow, considering the outcome of their conduct. Jesus Christ is the same yesterday, today, and forever.” (Heb. 13:5-8)

Finally, our Lord Jesus Christ’s truth is unchanging. He said "Heaven and earth may pass away, but My words will by no means pass away." (Mt. 13:31)   We can place our whole life, our faith and trust in Him.  "Jesus Christ is the same yesterday, today, and forever." (Heb. 13:8)
