"Then said the Lord to him [Moses], put off thy shoes from thy feet: for the place where thou standest is holy ground." (Acts 7:33)
I've seen preachers take their shoes off before they preached, the idea being that when they stood there, they were standing on holy ground. (I suppose this could indicate either humility or pride.) One thing I do know, however, is that when God told him to remove his precious sandals, Moses was not standing behind a pulpit; he was standing in the presence of God. And anyone who finds himself or herself in such a place will feel anything that might render him or her earth-bound—even shoes, would be too heavy!
Sometimes it's tempting to attach inordinate significance to an object, a place, or a position, that goes beyond that which God has prescribed. This is not to rob anything or anyone of legitimate respect, only to caution against Nicolaitanism or idolatry. But, more importantly, it's an exhortation not to miss those places of significance in our own lives. After all, wherever God condescends to meet with one of His children is holy ground, whether it be a desert, a mountain-top……or a rocking chair.
