1 Peter 4: 12 - 13

¹²Beloved, think it not strange concerning the fiery trial which is to try you, as though some strange thing happened unto you:
¹³But rejoice, inasmuch as ye are partakers of Christ's sufferings; that, when his glory shall be revealed, ye may be glad also with exceeding joy.

²⁴Be of good courage, and he shall strengthen your heart, all ye that hope in the LORD.

Romans 8: 24 - 28

²⁴For we are saved by hope: but hope that is seen is not hope: for what a man seeth, why doth he yet hope for?
²⁵But if we hope for that we see not, then do we with patience wait for it.
²⁶Likewise the Spirit also helpeth our infirmities: for we know not what we should pray for as we ought: but the Spirit itself maketh intercession for us with groanings which cannot be uttered.
²⁷And he that searcheth the hearts knoweth what is the mind of the Spirit, because he maketh intercession for the saints according to the will of God.
²⁸And we know that all things work together for good to them that love God, to them who are the called according to his purpose.

⁶He that goeth forth and weepeth, bearing precious seed, shall doubtless come again with rejoicing, bringing his sheaves with him.

²²And ye now therefore have sorrow: but I will see you again, and your heart shall rejoice, and your joy no man taketh from you.
