What the Lord is and what the Lord does is virtually identical to what the Word is and what the Word does:
Eternal
Ps 119:89 Forever, O Lord, Your word is settled in heaven.
Is 40:7 The grass withers, the flower fades,
When the breath of the Lord blows upon it; Surely the people are grass.
8 The grass withers, the flower fades, But the word of our God stands forever.
Matt 24:35 Heaven and earth will pass away, but My words will not pass away.
True
Ps 119:160 The sum of Your word is truth,
And every one of Your righteous ordinances is everlasting.
John 17:17 Sanctify them in the truth; Your word is truth.
Living
John 6:63 It is the Spirit who gives life; the flesh profits nothing; the words that I have spoken to you are spirit and are life.
Heb 4:12 For the word of God is living and active and sharper than any two-edged sword, and piercing as far as the division of soul and spirit, of both joints and marrow, and able to judge the thoughts and intentions of the heart. 13 And there is no creature hidden from His sight, but all things are open and laid bare to the eyes of Him with whom we have to do.
Powerful
Ps 107:19 Then they cried out to the Lord in their trouble;
He saved them out of their distresses. 20 He sent His word and healed them, And delivered them from their destructions.
1 Thess 2:13 For this reason we also constantly thank God that when you received the word of God which you heard from us, you accepted it not as the word of men, but for what it really is, the word of God, which also performs its work in you who believe.
