1 Peter 5:5–6 (ASV)
5Likewise, ye younger, be subject unto the elder. Yea, all of you gird yourselves with humility, to serve one another: for God resisteth the proud, but giveth grace to the humble. 6Humble yourselves therefore under the mighty hand of God, that he may exalt you in due time;

In time God honored this humility and exalted Mr. Müller, who would go on to have a much wider and deeper witness for Christ not only in Bristol, but around the world.
To the very end of his life, in spite of what others may have thought about his great faith, George Müller was conscious of his weakness and great dependence upon God to support him and keep him on the narrow path.
