Patriarchal Blessing of Chandler Rogers [by] Joseph Smith, Sr. ... Thou shalt do many miracles in the name of the Lord Jesus ... If thou art faithful thou shalt receive the ministration of angels; thy life shall be lengthened but, thy years shall be many, no power shall take thy life if thou wilt put thy trust in God. ... I seal thee up against the Destroyer. Satan shall not have power over thee. ... This is thy blessing, it is given thee on condition of keeping the commandments and the Word of Wisdom I seal thee up to eternal life. Amen.
