“Omnipotent” is derived from two Latin words: omni - "all" + potens - “powerful.”
It literally means "all powerful.”
“The Lord appeared to Abram and said to him, ‘I am God Almighty’” (Gen 17:1).
God introduced Himself to Abram this way because “since the creation of the world His invisible attributes, His eternal power and divine nature, have been clearly seen, being understood through what has been made” (Rom 1:20).
For Jeremiah as well, the creation was the evidence of God’s unlimited power.
“Ah, Lord God! Behold, You have made the heavens and the earth by Your great power and by Your outstretched arm! Nothing is too difficult for You” (Jer 32:17).
He Who possesses infinite power is infinite Spirit. There is no physical property to His being. Jeremiah pictures God’s action in creating as what any powerful action by a man requires — “an outstretched arm.” In His act of creating, God did not exert Himself more than speaking.
“By the word of the Lord the heavens were made,
And all their hosts by the breath of His mouth. . . .
For He spoke, and it was done;
He commanded, and it stood fast” (Ps 33:6, 9).
Only one thing can explain the ongoing existence of matter and animate life in this world from generation to generation:
“He is before all things
And in Him all things hold together” (Col 1:17)
“Lift up your eyes on high
And see Who has created these stars,
The One Who leads forth their host by number, , , ,
Because of the greatness of His might and the strength of His power,
Not one of them is missing” (Isa 40:26).
“He upholds all things by the word of His power” (Heb 1:3).
“. . . In Whose hand is the life of every living thing
And the breath of all mankind” (Job 12:10).
“He Himself gives to all life and breath and all things; . . . for in Him we live and move and have our being . . . “ (Acts 17:25, 28).
Every ability, strength, accomplishment, natural phenomenon, and technological achievement the world has ever known is, first of all, the exercise and demonstration of God’s creating, sustaining power. The ability of anyone or anything to function — indeed, its very existence — depends constantly on Him.
“They all wait for You
To give them their food in due season. . . .
You hide Your face, they are dismayed;
You take away their spirit, they expire
And return to their dust.
You send forth Your Spirit, they are created;
And You renew the face of the ground.
Let the glory of the Lord endure forever!
Let the Lord be glad in His works!” (Ps 104:27, 29-31)
God is not limited to doing what He has done or to all He ever will do. All of the expressions of His power together will only be finite. The power He possesses in His Person is immeasurably, infinitely greater. He is absolutely powerful.
“The Lord said to Moses, ‘Is the Lord’s power limited?’” (Num 11:23).
“With God nothing will be impossible” (Luke 1:37).
