All believers get to examine themselves in their own faith, because all things have been given to all believers, sufficiency is not in the believer but in and of God.
1 Corinthians 3:22 Whether Paul, or Apollos, or Cephas, or the world, or life, or death, or things present, or things to come; all are yours;
2 Corinthians 3:5 Not that we are sufficient of ourselves to think any thing as of ourselves; but our sufficiency is of God;
2 Corinthians 10:7 Do ye look on things after the outward appearance? If any man trust to himself that he is Christ's, let him of himself think this again, that, as he is Christ's, even so are we Christ's.
2 Corinthians 13:5 Examine yourselves, whether ye be in the faith; prove your own selves. Know ye not your own selves, how that Jesus Christ is in you, except ye be reprobates?
2 Corinthians 13:7 Now I pray to God that ye do no evil; not that we should appear approved, but that ye should do that which is honest, though we be as reprobates.
Luke 22:26 But ye shall not be so: but he that is greatest among you, let him be as the younger; and he that is chief, as he that doth serve.
