In the Beginning

Daniel 2:
20 God's name be praised from age to eternal age!
Wisdom and might are his!
21 God is the one who changes times and eras,
He is the One who dethrones one king, only to establish another,
He is the One who grants wisdom to the wise
and knowledge to those with insight.    (Common English Bible)

We human beings are creatures of time and space. Time and space came about when God made the beginning. Outside of the time-and-space bubble that we live in, there is eternity. That's why God had to create a "beginning".
Genesis 1 : 1
In the beginning God created the heavens and the earth.

Evidently, since God made the beginning, He must live outside of time and space. The book of Daniel quoted above, lets us know that God is the one who changes and controls times and eras of human history. Therefore, God has a timetable for the heavens and the earth to which He is sticking. Where there is a beginning, there is also an ending.

Here's another look at the beginning:
John 1:
1 In the beginning was the Word and the Word was with God and the Word was God.
2 The Word was with God in the beginning.
3 Everything came into being through the Word, and without the Word nothing came into being. What came into being
4 through the Word was life, and the life was the light for all people. . . . .
14 The Word became flesh and made his home among us.
We have seen his glory, glory like that of a father's only son, full of grace and truth.
(Common English Bible)

This "Word" which was in the beginning is not what the dictionary describes as "a pronounceable series of letters having a distinct meaning".
This "Word" is a divine Person, who was involved with causing the creation to come into being, and was already there before the beginning.
Later on this "Word" also took on a beginning, this time as a human being.

The Apostle Paul describes Him in this way:
Philippians 2:
5 Adopt the attitude that was in Christ Jesus:
6 Though he was in the form of God,
he did not consider being equal with God something to exploit.
7 But he emptied himself by taking the form of a slave
and by becoming like human beings.
When he found himself in the form of a human,
8 he humbled himself by becoming obedient to the point of death,
even death on a cross.
9 Therefore, God highly honored him
and gave him the name above all names,
10 so that at the name of Jesus everyone
in heaven, on earth, and under the earth might bow
11 and every tongue confess
that Jesus Christ is Lord,
to the glory of God the Father.    (Common English Bible)
In this letter to the Philippian Christians, the Apostle Paul gives us a summary of the life of the Lord Jesus Christ, who is the "Word".
We also discover that God has now given Him the highest name in heaven.
And the book of Revelation talks about the beginning and the end this way:
Revelation 1:
7 Look, [Jesus] is coming with the clouds! Every eye will see him, including those who pierced him, and all the tribes of the earth will mourn because of him. This is so. Amen.
8 "I am the Alpha and the Omega," says the Lord God, "the one who is and was and is coming, the Almighty."    (Common English Bible)
Revelation 21:
5 Then the one seated on the throne said, "Look! I'm making all things new."
He also said, "Write this down, for these words are trustworthy and true."
6 Then he said to me, "All is done. I am the Alpha and the Omega, the beginning and the end. To the thirsty I will freely give water from the life-giving spring.    (Common English Bible)
Revelation 22:   [Jesus said:]
12 "Look! I'm coming soon. My reward is with me, to repay all people as their actions deserve.
13 I am the Alpha and the Omega, the first and the last, the beginning and the end.    (Common English Bible)

This then is the the beginning and the end of the human story: it is all wrapped up in the Lord Jesus Christ, the Word, the Alpha and the Omega, the first and the last, the beginning and the end.

Lord Jesus Christ,
today I confess that Your name is above all others in heaven, on earth and under the earth.
I bow my knee before You today and give You my life,
