There is too wide a gap, for most of us, between what we say and what we mean. Between our words and our thoughts. The first thing the Prophet Isaiah said when he saw the living and exalted God was, “Woe is me, I am ruined. For I am a man of unclean lips and I live among a people of unclean lips” (Isaiah 6:5). Isaiah was one of the most godly men who ever walked the earth. But seeing God, he sees also, abrupt and stark and grief-making, his own duplicity. Then God does what only God can do: he sears his lips clean (Isaiah 6:6-7). And herein lies our hope: truly seeing God, we truly see ourselves, in all our woe-begotten duplicity; but crying out to God, we are truly and greatly helped.
