Thematic Bible: Qualified by God

And I say, 'Woe to me, for I have been silent, For a man -- unclean of lips am I, And in midst of a people unclean of lips I am dwelling, Because the King, Jehovah of Hosts, have my eyes seen.' And flee unto me doth one of the seraphs, and in his hand a burning coal, (with tongs he hath taken it from off the altar,) and he striketh against my mouth, and saith: 'Lo, this hath stricken against thy lips, And turned aside is thine iniquity, And thy sin is covered.'

not that we are sufficient of ourselves to think anything, as of ourselves, but our sufficiency is of God, who also made us sufficient to be ministrants of a new covenant, not of letter, but of spirit; for the letter doth kill, and the spirit doth make alive.
