2 Corinthians 10:11
Let such an one think this, that, such as we are in word by letters when we are absent, such will we be also in deed when we are present. Let such an one think this, that, such as we are in word by letters when we are absent, such will we be also in deed when we are present.
The verse vindicates Paul's course of preaching the gospel in disinterested love for souls while supporting himself by his own tentmaking labor. He met his own expenses by working at his trade so that his ministry would be free from any charge of self-seeking. His accusers turned that self-support against him, charging that he was bold by letters when absent but base and humble in presence because he stooped to do mechanical work. They said his letters were weighty and powerful, while his bodily presence was weak and his speech contemptible.
To such critics the verse gives warning that what he is in word by letters when absent he will also be in deed when present. He declares that he is about to speak decidedly and to act with the same firmness in person that he had shown in writing. His humble conduct while present, including his willingness to do manual work, did not mean he lacked apostolic authority or would fail to carry out what he had written.
