Charles H. Spurgeon on Psalms 47:2

The Lord most high is terrible. Christ is terrible, that is, fearful, or meet to be feared, not of his children only for their good, but of the wicked also for their punishment; terrible to the devil, as being stronger than he, casting out the prince of darkness by the finger of God. Lu 11:22 Joh 12:31. And therefore so soon as an unclean spirit saw Jesus, he cried out, "What have we to do with thee, thou Jesus of Nazareth? art thou come to destroy us?" Mr 1:24; or as other devils, Mt 8:29, "Art thou come hither to torment us before the time?" for the devils in believing tremble. Terrible to hypocrites, and other impious agents of the devil, as having his fan in his hand to make clean his floor, and to gather his wheat into his garner, but he will burn up the chaff with unquenchable fire. Mt 3:12. Or Christ is excelsus in potentia, terribilis in justitia; high in power, and fearful in justice; high in exalting the good, and terrible in humbling the bad. John Boys.
