'Word' in the Bible

For the word of the cross is foolishness to those who are dying, but to us who are saved it is the power of God.

But I will come to you shortly, if the Lord is willing. And I will know, not the word of those who are puffed up, but the power.

For the Kingdom of God is not in word, but in power.

For to one is given through the Spirit the word of wisdom, and to another the word of knowledge, according to the same Spirit;

What? Was it from you that the word of God went out? Or did it come to you alone?

by which also you are saved, if you hold firmly the word which I preached to you -- unless you believed in vain.
