This line is from Francis Thompson’s poem, The Mistress of Vision. To me it is suggestive of two things. First, Francis Thompson wrote many poems that should be of interest to Christians, not the least of which is The Hound of Heaven. Here he suggests that the interrelationships of all nature may be far more complex and interrelated than we first realize. It encourages a Christian to ponder and, paraphrasing St. Augustine, to behold and see that it is all beautiful. In so doing we see that the beauty in nature is its confession to God and could not have been created or exist without His intervention.
Secondly, this line encourages us to ponder more deeply the things we do and say and even think. The consequences of our actions may be both unexpected and far reaching.
