Weed

"But while everyone was sleeping, his enemy came and sowed weeds among the wheat, and went away." Matthew 13.25

While the children of light sleep and get distracted, the devil sows his children in their midst to corrupt them and draw them back to darkness, whether it is through dating, marriage or any other form of partnerships.
Those who are wise are careful not to get involved with the children of darkness under any circumstances.

Iniquity

"The fool has said in his heart,'There is no God.' They are corrupt, and have done abominable iniquity; There is none who does good."

Psalm 53:1

In search of self satisfaction through all kinds of entertainment, people have ignored the existence of God, and with that destroying one self and others around them.
