'Power of God' in the Bible

For the message of the cross is foolishness [absurd and illogical] to those who are perishing and spiritually dead [because they reject it], but to us who are being saved [by God’s grace] it is [the manifestation of] the power of God.

but to those who are the called, both Jews and Greeks (Gentiles), Christ is the power of God and the wisdom of God.

And my message and my preaching were not in persuasive words of wisdom [using clever rhetoric], but [they were delivered] in demonstration of the [Holy] Spirit [operating through me] and of [His] power [stirring the minds of the listeners and persuading them],

so that your faith would not rest on the wisdom and rhetoric of men, but on the power of God.

and all [of them] drank the same spiritual drink, for they were drinking from a spiritual rock which followed them; and the rock was Christ.
