Today we as God's people need to devote more thoughtful, prayerful attention to the work being carried on in our behalf in the heavenly sanctuary. We are living in the antitypical Day of Atonement, and God expects much of those who compose His remnant church. "While the investigative judgment is going forward in heaven, while the sins of penitent believers are being removed from the sanctuary, there is to be a special work of purification, of putting away of sin, among God's people upon earth" (The Great Controversy, pg. 425).
God's last-generation people are to reveal the character of Jesus to the world. They will overcome as He overcame. They will be victorious, living representatives of the Master, The enabling power to live this life, to achieve this character, comes from Jesus. Only through His imputed and imparted righteousness can we prevail.
The sanctuary service has many lessons for us as we prepare to meet our soon-coming Lord. Elder Frazee treats these beautifully. After hearing his series I encouraged him to put the material in book form so that more might be blessed.
