Why should we suffer?

Now, if Christ was not exempted from sufferings, why should Christians expect it? If he suffered, to expiate sins, why should not we be content when our sufferings are only for trial and correction, but not for expiation? If he, though perfectly just, why should not we, who are all criminals? If he once suffered, and then entered into glory, shall not we be patient under trouble, since it will be but a little time and we shall follow him to glory? If he suffered, to bring us to God, shall not we submit to difficulties, since they are of so much use to quicken us in our return to God, and in the performance of our duty to him?
