Romans
9 I say the truth in Christ, I lie not, my conscience also bearing me witness in the Holy Ghost,

[SUP]3 [/SUP]For I could wish that myself were accursed from Christ for my brethren, my kinsmen according to the flesh:
Psalm 126
[SUP]5 [/SUP]They that sow in tears shall reap in joy.
[SUP]6 [/SUP]He that goeth forth and weepeth, bearing precious seed, shall doubtless come again with rejoicing, bringing his sheaves with him.
Ecclesiastes 7

[SUP]3 [/SUP]
Sorrow is better than laughter: for by the sadness of the countenance the heart is made better.
[SUP]4 [/SUP]The heart of the wise is in the house of mourning; but the heart of fools is in the house of mirth.
