People who appear confident or forthright are not necessarily proud. (John 1:46, 47) Yet, whether we are outgoing or not, all of us must work at developing a humble heart condition. Consider the example of the apostle Paul. He was used mightily by Jehovah to establish new congregations in one city after another. He may even have accomplished more in the ministry than any other apostle of Jesus Christ. Yet, Paul did not elevate himself among his brothers. He correctly attributed his fine standing with Jehovah, not to his own qualities or works, but to God’s undeserved kindness. (1 Cor. 15:10) What a fine lesson in humility Paul gave in his letter to the Corinthians​—especially when we recall that some men in the congregation were seeking to prove themselves to be superior to Paul!​—2 Cor. 10:10. w19.09 3 ¶5-6
