What’s the difference between a bridge and a doormat?  A bridge takes you somewhere.  Paul tells us that we should please our neighbors, “for their good, to build them up.”  Therefore, forbearance is not placation.  Rather it is a call to be part of the process of growing as God walks with them from where they are to where HE wants them to be, which may not be where your liberty, theology and life experience would expect them to be.  As He walks with them they may end up walking on us as we act as a bridge to them after the fashion that Christ has been a bridge for us
