People living in the holy land would have been familiar with the dangers of weeds growing up around the wheat and how difficult it is to tell the difference between them until they bloomed. The wheat of course represents good and weeds, evil. As Christians, we need to tell the difference between them especially in a world that makes them seem the same.
The devil’s strongest tool against us is the lie. He uses deception to cloud our perception and convince us that we are not responsible for our actions. That somehow, we can do everything alone and without God. As Christians, understanding good and evil, and taking responsibility for our choices is all about discovering the Truth that is God. God is not a figment of our imagination. He is real and a separate person from us. God is equally merciful and just. We can never be afraid to face the truth even if it makes us feel ashamed, or embarrassed. Because Truth is of God.
