Although the Sandemanians thus held many views that were accurately based on Scripture, they did not grasp the importance of the very activity that characterizes true Christians, namely, that each should preach the Kingdom good news to others.
Kuigi paljud sandemanlaste vaated põhinesid täpselt Pühakirjal, ei mõistnud nad, kui suur tähtsus on just sellel tegevusel, millest tõelisi kristlasi tuntakse, nimelt igaühe kohustusel kuulutada Kuningriigi head sõnumit ka teistele.
