Joy keeps onward and doesn’t back down

Example:

When I heard, my belly trembled; my lips quivered at the voice: rottenness entered into my bones, and I trembled in myself, that I might rest in the day of trouble: when he cometh up unto the people, he will invade them with his troops. Although the fig tree shall not blossom, neither shall fruit be in the vines; the labour of the olive shall fail, and the fields shall yield no meat; the flock shall be cut off from the fold, and there shall be no herd in the stalls: Yet I will rejoice in the Lord, I will joy in the God of my salvation. The Lord God is my strength, and he will make my feet like hinds' feet, and he will make me to walk upon mine high places. To the chief singer on my stringed instruments.
