The seal, or evidence, of the apostolic gift is the spiritual result it brings in the lives of others. Paul wrote to the church at Corinth which he had organized: Of the seal of mine apostleship are ye in the Lord. (I Corinthians 9:2b)
…Sapagkat ang tatak ng aking pagkaapostol ay kayo sa Panginoon. (I Corinto 9: 2b)
