Why: take refuge in him alone with your whole being, by his grace you shall attain supreme peace and the eternal abode, giving direct, personal instruction rather than only continuing the more impersonal, mechanistic description from the previous verse.

In life: sometimes, after a period of feeling caught within larger, impersonal forces, what actually helps most is a direct, personal instruction, something concrete you can actually orient toward, rather than continuing to only describe the larger, impersonal mechanism.

Teaching: after acknowledging the larger, impersonal forces shaping your circumstances, look for the direct, personal action you can actually take in response, orienting toward something concrete, rather than remaining stuck only in the more abstract, impersonal description of your situation.
