They would be sorted out later, when the Son of Man comes into his kingdom. If you cannot trust God to bring in the kingdom you might well think it is your job to sort out the wheat from the weeds. The Christian faith leads us to expect fulfilment of God's purpose that we human beings should fulfill our potential to become children of God. While we wait we have no need to be ashamed of what we believe. The difference does matter.
Faithfulness is required while the wheat and the weeds grow together.
By his great mercy we have been born anew to a living hope through he resurrection of Jesus Christ from the dead. Most merciful God we confess that we have sinned against you and our neighbour. We have taken great benefits with little thanks and we have been more ready to insist upon our rights than to see the needs of others. Have mercy and forgive us, for the sake of Jesus Christ our Lord. Thanks be to God.
