Blessed be the God and Father of our Lord Jesus Christ!

According to his great mercy, he has caused us to be born again to a living hope through the resurrection of Jesus Christ from the dead, to an inheritance that is imperishable, undefiled, and unfading, kept in heaven for you, who by God's power are being guarded through faith for a salvation ready to be revealed in the last time.

In this you rejoice, though now for a little while, if necessary, you have been grieved by various trials, so that the tested genuineness of your faithŚmore precious than gold that perishes though it is tested by fireŚmay be found to result in praise and glory and honor at the revelation of Jesus Christ.

Though you have not seen him, you love him.

Though you do not now see him, you believe in him and rejoice with joy that is inexpressible and filled with glory, obtaining the outcome of your faith, the salvation of your souls.
1Peter 1 1-9

But it seems somewhat inconsistent, when he says that the faithful, who exulted with joy, were at the same time sorrowful, for these are contrary feelings.

But the faithful know by experience, how these things can exist together, much better than can be expressed in words.

However, to explain the matter in a few words, we may say that the faithful are not logs of wood, nor have they so divested themselves of human feelings, but that they are affected with sorrow, fear, danger, and feel poverty as an evil, and persecutions as hard and difficult to be borne. Hence they experience sorrow from evils; but it is so mitigated by faith, that they cease not at the same time to rejoice. Thus sorrow does not prevent their joy, but, on the contrary, give place to it.

Again, though joy overcomes sorrow, yet it does not put an end to it, for it does not divest us of humanity.

And hence it appears what true patience is; its beginning, and, as it were, its root, is the knowledge of God's blessings, especially of that gratuitous adoption with which he has favored us; for all who raise hither their minds, find it an easy thing calmly to bear all evils. For whence is it that our minds are pressed down with grief, except that we have no participation of spiritual things? But all they who regard their troubles as necessary trials for their salvation, not only rise above them, but also turn them to an occasion of joy.
