Like the field in the parable there is good seed and there are weeds even in the world in which we live. There is both good and evil. We are called to take only what is good and not focus too much on the evil or bad. This does not mean passivity in the face of evil but a call for a discerning mind and heart.
Are you too quick to judge others ONLY by their external actions? Will you refrain from ALL judgement today?
