The literature concerning nonlocal boundary value problems is extensive. Moreover, applications of fixed point theorems to positive solutions of such has sparked much interest, see [9, 10, 11, 12]. Many of the results involving nonlocal boundary value problems are summarized in [9]. A more general summary of positive solutions results for a variety of differential equation types is available in [1]. Our interest lies in the nature of nonlocal problems as being the limiting problem of more classical focal problems. For example, we will consider the second order, three-point BVP
