One of the strange aspects of the conventional mind is its resistance to change. It likes to stay in its familiar ruts, even though they are limiting, even harmful.
But difficult circumstances frequently light mental fires under us and get us up, out, and moving. These fiery goads are not generally accepted with joy, but they are salutary in their effect. Whether we like it or not, they force growth upward.
Similarly, reluctance to leave material standpoints and grow in the things of Spirit is sometimes a failing of students of Christian Science. Some of us are quite content to laze along happily in well-established material patterns of thought and action until we are forced out of our inertia by a challenging experience.
