I'm a woman on a journey. It hasn't all been hard and it hasn't all been easy. Sort of like walking on the sand. Sometimes the sand is firm and cool beneath your feet and your stride is sure. Sometimes the sand is deep and soft and your calves burn and your thighs and lungs ache as you trudge along. Sometimes you get stuck in the sand and sometimes it blows in your face. But when God said to Abraham "Go", there was no discourse about the sand. He just went.
Just in case you wanted to know - "Walking on sand requires 2.1–2.7 times more energy expenditure than does walking on a hard surface at the same speed;" from - MECHANICS AND ENERGETICS OF HUMAN LOCOMOTION ON SAND, T.

No wonder I'm tired.
