What does the Bible say about the characteristics of believers?

In Scripture, believers are often compared to doves, symbolizing their purity, gentleness, and mourning over sin. For example, in Isaiah 60:8, they are described as flying like doves to their windows, indicating a desire for safety and fellowship with God. This imagery connects with the idea that genuine believers are aware of their sinful condition and seek the Savior, mourning like doves over their iniquities. Isaiah also highlights the outpouring of grace in dark times, illustrating the contrast between the oppression caused by sin and the hope found in the light of Christ's coming.
