That mean the flow got wings and it come from the dirt
His Flow, is Heavenly like an Angel, and came the from the bottom, “Wings” like chicken wings, and the dirt being a reference to a common Bible saying, “ashes to ashes, dust to dust”, used as an allegory for his flow coming from the dirt.
All this comes together with subtle word play: lake/flows chicken/wings comes from the dirt/church.
The two lines both deal with Jesus' birth and rise from the mud and dirt. Like Jesus, Common and his flow came from nothing and rose to the top. Southside Chicago is his own personal Bethlehem, making the rapper the second coming of lyrical talent.
