Here Paul solemnly charges Timothy to be diligent, though many will not hear nor accept sound doctrine. He enforces the charge by mentioning his martyrdom, soon to come. He asks Timothy to get in a hurry to get to him and be sure to bring his books and his notes and writing materials. He cautions Timothy, and complains of how the brothers he depended on had deserted him; and expresses how even though they abandoned him his faith was not shaken because he was assured of his own preservation to the heavenly kingdom. Sometimes people will fail you and give up when the going gets tough, but you can always depend on God. He promised never to leave nor forsake us.
