Matthew 13:24-30 The parable of the weeds among the wheat:
Jesus says, "The kingdom of heaven may be likened to a man who sowed good seed in his field . . . the enemy came and sowed weeds . . . the crop grew and bore fruit, the weeds appeared as well . . . His servants asked, 'Do you want us to pull up the weeds?' Jesus said, 'No, if you pull up the weeds you might uproot the wheat along with them. Let them grow together until the harvest. . . . at that time, harvesters will 'First, collect the weeds and tie them up for burning; but gather the wheat into my barn.'"
Wheat and weeds grow together "in the soil" that is each one of us. We don't want to "feed" the "bad stuff", but we naturally do because "we are soil".
God, in His wisdom, knows this! Though we would never feed a weed (or I can't say I know anyone that does) . . . they grow. Though I try to prevent the growth and spread of weeds, they still pop up. When all is said and done for us in life here on earth, God is going to take from us "our weeds" and He's going to LOVE the good stuff!
