How can we bring up God's omnipotence (His all-powerfulness) and try (as we're wont to do) to encapsulate it in as few words as possible? There is practicality in succinctness. If you feel you need to read St. Thomas Aquinas’ Summa Thologica, then by all means. I'll wait right here.
And if you still have a hankering for something that you can't put your finger on, may I suggest the "simplicity of Christ" (2 Corinthians 11:3)? Jesus said that all power in Heaven and earth was given to Him (Matthew 28:18). He said this prior to sending His disciples out on the "great commission", which was to take the Gospel all over the world. It should be understood that the disciples received their power from Jesus, who in turn received His power from His Father. A closed loop. Whenever we partake of God's work in this world, whether it's feeding the homeless in our cities or adopting orphans from Africa, or smiling at someone to show them God's love, it's all from the same power source. From God Himself. The confidence needed to do any of these things—at any stage therein—is the power of God. As much as you need. "Power on earth to forgive sins" (Matthew 9:6). Power to overcome and do whatever God has called you to do. "All things" as Peter wrote. (2 Peter 1:3).
"I can do all things through Christ which strengtheneth me." (Philippians 4:13)
Plenipotence is a word you may not hear too often. As opposed to all power which is solely God's, plenipotence is distinct in that it means full power. In other words, all the power you can contain. The more power you need for the task at hand, the better it is. "All power on Heaven and earth" belongs to Jesus and it's ours for the asking. "How shall He not with Him (Jesus, He’s first), also freely give us all things?" (Romans 8:32). Plenipotence is possible.
In closing, a closed circuit, or closed loop, means that the power can flow. The appliance can turn on. The more of God's word that we both memorize and meditate upon—like wires and circuitry—the more power we can receive to do God's work in this world.
Unlike a snake that devours its own tail (the Ourobouros of myth) and symbolizing a completed cycle, God’s power is self-perpetuating, in and of Himself. His power is not divorced from His person. Rest in Him.
