My space is literally 'my space'. Your space can be wherever you find peace and quiet. A space where your can get in touch with your inner man. Your inner man is where you find peace and joy when every thing around you is chaotic. It's where God lives. Sometimes, my space is on the boardwalk watching the waves crash against the rocks, other times its in my bathtub in the dark with a fragrant candle. Whichever, my space always gets me in touch with my inner man where God talks with me and renews my Spirit. We can barely handle the externals, only God can change the inward parts where He speaks to the heart.
Psalm 51:6 says, 'Behold, You desire truth in the inward parts: and in the hidden part You shall make me to know wisdom.'
