Where does EGW describe God's throne as being on earth?

"Having given Jesus, the great Gift, God gave all heaven with Him. He would bless immeasurably the great groundwork of the redemption of a lost world; He would surround the world with favours; He would heap gift on gift; and He opens for all who, through faith in Christ, will receive His gift, the treasures of eternal life. He established His throne on earth by the Holy Spirit's power, to convince the world of sin, of righteousness, and of judgment; that Christ, through His Holy Spirit, might live in all the powers of the soul, sending through it a perpetual current of joy and blessedness in obedience to all of God's commandments. These commandments are given to counter-work the working of Satan, who impels the human family to disobedience of God's plainly expressed will." {BEcho, June 17, 1895 par. 4}
