Thus we see that He has mind, will, and emotions.

He comforts. Acts 9:31. He helps our infirmities. Rom. 8:26. He intercedes for the saints. Rom. 8:26. He searches the deep things of God. 1 Cor. 2:10. He sanctifies. Rom. 15:16. He witnesses. Rom. 8:16. And He commands. Acts 16:6,7. He is susceptible to personal treatment. He can be lied to. Acts 5:3. He can be resisted. Acts 7:51. He can be blasphemed. Matt. 12:31,32. He can be grieved. Eph. 4:30. And He can be quenched. 1 Thess. 5:19.’
