You can sing; when the problems roar and roll in like sea billows, you can just sing like the hymnist: it is well with my soul!

Yes, what else would you say other than It is well?  Whatever your lot, let your Lord teach you to say: It is Well.  This is one of the greatest attitudes to breakthrough.

2Kings 4: 23-28 (NKJV)     

And she said, “It is well.” 24 Then she saddled a donkey, and said to her servant, “Drive, and go forward; do not slacken the pace for me unless I tell you.” 25 And so she departed, and went to the man of God at Mount Carmel.
So it was, when the man of God saw her afar off, that he said to his servant Gehazi, “Look, the Shunammite woman! 26 Please run now to meet her, and say to her, ‘Is it well with you? Is it well with your husband? Is it well with the child?’”
And she answered, “It is well.”
