What does it mean that God's wrath is restrained?

God's restraint of wrath signifies His mercy towards sinners saved by grace. In Noah's account, the floodwater represents God's fierce judgment against unrepentant sin; however, for Noah and his family within the ark, that wrath was held back. For believers today, this restraint means that while they continue to struggle with sin, they are not subject to God's judgment because that wrath was fully absorbed by Christ on the cross. This foundational truth brings great comfort, ensuring that believers can live without fear of condemnation, fully recognizing that their sins have been dealt with and they are free to approach God with confidence.
