"They are not all Israel who are of Israel: a man, by a literal circumcision, may be a Jew outwardly; but the circumcision of the heart by the Spirit makes a man a Jew inwardly...those who pretend that, although they are unholy in themselves, they are reputed holy in Christ, because His righteousness is imputed to them, most awfully deceive their own souls...Let none deceive themselves; sanctification is a qualification indispensably necessary to them who will be under the conduct of the Lord Christ unto salvation; He leads none to heaven, but whom He sanctifies on earth. The holy God will not receive unholy persons. The living head will not admit of dead members..."
One pastor illustrated it like this: he was weeding in his garden when his little boy wanted to help. So he allowed it. After a while, looking back, he found that his little one had not only pulled the weeds, but the baby plants which had been growing. His child earnestly wanted to please his daddy though he did not know what he was doing. ("Father forgive them for they know not what they are doing.")
Sometimes people of holiness do make mistakes, and hopefully we do epitomize humility and apologize when wrong. But it doesn't change the fact that God is pleased with our willingness to follow Him and His example wholeheartedly with a heart filled with His Spirit, even if we tug on the wrong thing once in awhile. Holiness people should be open to correction by His word, always growing.
