Rooted but Flexible

Heard this the other day:  The  principles never change,  but the  methods  always do .   What a solid management philosophy this makes for us Christ followers. Principles are defined as:   fundamental truths that serve as the foundation for a system of beliefs.  Our biblical core beliefs are the basis of who we are and what we do. And that applies to how we  work,  lead  and manage . But the methods,  those change  based on the circumstances and the people involved.  So  we need to be  flexible , not  rigid . Deeply rooted, but like the branches of a tree, sway with the wind. So how about you? Are your principles well rooted but flexible enough  for change ?
