Question: what scripture says it is well with my soul?
Answer: At the sound of the final trumpet, the Lord will begin to make His return to earth (1 Corinthians 15:52, 1 Thessalonians 4:16, and Revelation 11:15). Even so, it is well with my soul. Saved from the wrath of God, we can enjoy eternal bliss with Him forever (Revelation 21:1-4).
