What does it mean that the ungodly are like chaff?

The sermon explains that the ungodly are compared to chaff, which is the worthless husk of grain that is blown away during the winnowing process. This imagery illustrates the fate of those who reject God's law and counsel. Just as chaff is discarded and has no lasting value, the ungodly will not stand in the judgment, as they will be separated from the righteous. Their lives, devoid of spiritual substance, will ultimately lead to their ruin, highlighting the stark contrast between the blessed man and the ungodly.
