I found this excerpt in C.H. Spurgeon's Morning and Evening the other night, and thought it was worth sharing. Especially because I like having such good company in prescribing a walk as a balm for all woes. :)
"Isaac went out to meditate in the field at the eventide." (Genesis 24:63)
...When Jesus is the theme, meditation is sweet indeed. Isaac found Rebekah while engaged in private thoughts. Very admirable was the choice of place. In the field we have innumerable texts for thought. From the cedar to the hyssop, from the soaring eagle to the chirping grasshopper, from the blue expanse of heaven to a drop of dew, all things are full of teaching. When the eye is divinely opened, that teaching flashes on the mind far more vividly than from written books. Our little rooms are neither so healthy, so suggestive, so agreeable, nor so inspiring as the fields. Let us count nothing common or unclean but feel that all created things point to their Maker, and the field will at once be hallowed. The glory of the setting sun excites our wonder, and the solemnity of approaching night awakens our awe. If the business of the day will permit it, it will be well, dear reader, if you can spare an hour to walk in the field in the evening. But if not, the Lord is in the town, too, and will meet with you in your room or in the crowded street. Let your heart go forth to meet Him.
