Thematic Bible: Qualified by God

And I said, "Woe to me! For I am destroyed! For I [am] a man {of unclean lips}, and I [am] living among a people {of unclean lips}, for my eyes have seen the king, Yahweh of hosts!" Then one of the seraphs flew to me, and in his hand [was] a hot coal he had taken from the altar with tongs. And he touched my mouth, and he said, "Look! This has touched your lips and has removed your guilt, and your sin is annulled."

Not that we are adequate in ourselves to consider anything as from ourselves, but our adequacy [is] from God, who also makes us adequate [as] servants of a new covenant, not of the letter, but of the Spirit, for the letter kills, but the Spirit gives life.
