In the first passage we have quoted we find that a few days before the death of the Lord Jesus some Sadducees questioned Him on the matter of resurrection. They said: “Now there were with us seven brethren: and the first married and deceased, and having no seed left his wife unto his brother; in like manner the second also, and the third, unto the seventh. And after them all, the woman died. In the resurrection therefore whose wife shall she be of the seven? for they all had her.” To them the Lord gave a most distinctive answer: “Ye do err, not knowing the scriptures, nor the power of God.” I do not intend to explain this complicated story, but will draw from this verse two profound principles which concern our spiritual life. The first is understanding the Scriptures and the second is knowing the power of God. These two principles indicate that a Christian should have two kinds of knowledge: first, the knowledge of the Scriptures, and second, the knowledge of the power of God.
