Omnipotence: adj. The state of being omnipotent; almighty power; hence, one who is omnipotent; the Deity. (Answers-The online dictionary)
Omnipotent: n. One having unlimited power or authority: (The Free Dictionary)
Omnipotent is a compound word from two Latin words, omnis, meaning all, and poetntia or potens which means power.
Omnipotence means infinite power. And, it is not limited to brute strength, but unlimited power in every respect. The term is accurate and fitting for the almighty God. This is not meant to say that God can make square circles or such juvenile incompatible acts. He is capable of doing anything He wishes to do. He was capable of speaking into existence, all matter which comprises this universe.
John, while in exile on the isle of Patmos wrote this: And I heard as it were the voice of a great multitude, and as the voice of many waters, and as the voice of mighty thunderings, saying, Alleluia: for the Lord God omnipotent reigneth. (Revelation 19:6 KJV)
And Paul wrote to the Colossians, concerning Jesus (who is God), this: For by him were all things created, that are in heaven, and that are in earth, visible and invisible, whether [they be] thrones, or dominions, or principalities, or powers: all things were created by him, and for him: And he is before all things, and by him all things consist. (Colossians 1:16-17 KJV)
The last phrase in the quote just above means that by Jesus all things hold together or continue to function. Paul, in fact, spends much of the chapter in praise of God the Father and the Son. It will be helpful for the student to read the entire chapter here.
God demonstrated His omnipotence many times throughout the Bible, not only the creation, but the massive world wide flood which he created when he decided to eliminate the evil populace. He also used mighty miracles to convince the Egyptian Pharaoh to allow his people to leave their captivity. And many other incidents. His inspired writers referred to His infinite strength. Here are several instances:
"Behold, I am the Lord, the God of all flesh: is there any thing too hard for me?" (Jeremiah 32:27 KJV)
"Hast thou not known? hast thou not heard, that the everlasting God, the Lord, the Creator of the ends of the earth, fainteth not, neither is weary? there is no searching of his understanding." (Isaiah 40:28 KJV)
"I know that thou canst do every thing, and that no thought can be withholden from thee." (Job 42:2 KJV)
"But Jesus beheld them, and said unto them, With men this is impossible; but with God all things are possible." (Matthew 19:26 KJV)
And finally, God's infinite power will be shown at the end of time, when all will bow before Him. Peter explains the enormous occurrence which will completely eradicate the creation and mark the ending of the material realm.
"The Lord is not slack concerning his promise, as some men count slackness; but is longsuffering to us-ward, not willing that any should perish, but that all should come to repentance. But the day of the Lord will come as a thief in the night; in the which the heavens shall pass away with a great noise, and the elements shall melt with fervent heat, the earth also and the works that are therein shall be burned up. Seeing then that all these things shall be dissolved, what manner of persons ought ye to be in all holy conversation and godliness, Looking for and hasting unto the coming of the day of God, wherein the heavens being on fire shall be dissolved, and the elements shall melt with fervent heat?" (2 Peter 3:9-12 KJV)
This incident will undoubtedly be the most gigantic of all God's displays of power. It could be some yet undiscovered by man, type of nuclear chain reaction which can permeate each existing atom. In the early years of nuclear experimentation, there was considerable concern of starting such a reaction. And now, with the perceived discovery of the Higgs boson particle, the question of total annihilation of all matter has been brought to the forefront once again.
Whether or not man can ever discover and cause such an end to the material realm, either purposely or accidentally, is not known. But we can know that the omnipotent God of heaven and earth, has that power at His disposal.
