This hymn was originally sung because of the letter.

The original singers of Song of Faith are Mei Qing and Han Yin. The lyrics of the hymn sung by faith are: because of faith, he left Ur. By faith, I gave my beloved son to him completely. Through letters, he walked near the Red Sea. By faith, even the tides are separated. By faith, some people were trapped in the lion's den, but they still worshipped God and vowed to die. With confidence, we have evidence. By faith, we found the promise together. Through faith, you can find that you are just a stranger in the world and return to a more beautiful hometown.
