Colossians 1:16

For by Him all things were created that are in heaven and that are on earth…
Colossians 1:16

The only way someone can know this is if someone was there when it happened to tell us. Someone was there, and that someone was the Holy Spirit. He always points to Jesus, and in this verse the Spirit reveals to us the fact of Jesus Christ as the creator of the universe. Some mock at this notion, yet no one can contradict on scientific grounds that Jesus created the universe. Consider the following illustration of the dilemma regarding the pendulum clock.
Suppose a scientist enters a room with a swinging pendulum. He has never seen one before. He records its movements and notes the slowing of it and the certainty of its soon ceasing of movement. He figures the equation to determine the exact time in the future which such will occur. His equation will indeed work.

He now decides to investigate the past. How long had the clock been running? How did the pendulum get started? Using his tested equation above he adjusts the factors and for a while the equation seems to work. However, the farther back in time he goes, his data begins to no longer make sense. The swing of the pendulum, according to the data, becomes greater and greater, now hitting the ceiling with each swing; in fact, swinging in two directions simultaneously. The conclusion is that his equation was an absurdity. There must be another explanation.

He can conclude and measure laws that govern the swing of the pendulum quite successfully. But those laws fail to explain the initial swing of the pendulum. Something dramatically different happened to initiate the pendulum movement.

What happened he does not know. The familiar laws of energy and motion do not extend that far. He can suggest a theory, but only that… theory. In truth he is speaking no longer as a scientist, but rather as a philosopher. Only revelation will with certainty satisfy his curiosity.

His best effort will be from reasoning. He lacks the advantage of revelation.

Only one who was present can answer the question “If the universe had a beginning, how did it begin?” That one simply and magnificently was Jesus Christ— “by Him all things were created.” Paul had no difficulty writing this. It was only a short time before that Jesus had been on earth. Many were still alive who knew Him, seen and heard Him. They had no problem with this incredible revelation of Paul. In fact, Paul had met Him face-to-face, seen Him in all glory, and knew Him as “the Lord from Heaven.” He had no doubts. His greatest determination was to know Him as “Christ crucified.” Earlier to the Corinthians he would write of this— “For the message of the cross is foolishness to those who are perishing, but to us who are being saved it is the power of God.”

Not only is Jesus our creator, but too He is our savior… that is good news!
