In his book on evangelism titled The Art of Manfishing (“follow me and I will make you fishers of men”), Thomas Boston writes this about the net of the gospel,
“the meshes must not be over-wide, lest the fish run through. So neither must thy doctrine be general, without particular application, lest thou be no fisher of men. Indeed men may be the better pleased, when thou preachest doctrine so as wicked men may run out-through and in-through it, than when thou makest it so as to take hold of them; but be not a servant of men” (p. 39).
So in the counsel of one wise Puritan, let us be like the ancient fishers – always mending and tightening our nets by making certain our theology is biblically sharp and earnestly applied.
