If there is one statement from the Spirit of Prophecy which has contributed to misinterpreting the character of God it is this one: "The work of destruction is a strange work to Him who is infinite in love." Patriarchs and Prophets, p.139.
Many have read this statement and thought it said something that it did not say at all. It does not say that the work of destruction is the work of God but that the work of destruction which is the work of Satan is a strange work for Him who is infinite in love.
"Satan is the destroyer." Testimonies, Vol.6, p.388,89.
On the other hand, "God's great and strange work is to redeem and save and thus repair the ruin that sin has made." E.G. White, Review and Herald, Vol.3, p.583.
God is continually at work counteracting the works of the devil. This is His great and strange work, not the work of destroying which is the work of Satan who is the destroyer.
