Word of God] Some understand it of the Word written or spoken, and of the great power thereof; whereof S. Paul speaks, 1 Corinthians 14:24. But with more probability, if observe both the antecedents and consequents of the place, we may understand it of Christ, who is called the Word, John 1. 1. Revelation 19:13. because he was to reveal the counsell and will of God his Father unto his people.
quick] living. Whereby he is opposed to the Idols of the Heathen, who had eyes and saw not, and ears and heard not, &c. but Christ the Word of God is living, beholding all the thoughts and actions of men, that so he might give to every man according to his deeds.
powerfull] He is not onely omniscient, but also full of power to execute his wrath upon those that are disobedient.
sharper] By this similitude is likewise expressed the Omniscience of Christ, unto whom nothing is secret, no not the thoughts and intentions of our hearts: A two-edged sword easily enters, it makes way for it selfe.
