Jesus told them this story: The kingdom of heaven is like what happened when a farmer scattered good seed in a field. But while everyone was sleeping, an enemy came and scattered weed seeds in the field and then left.
When the plants came up and began to ripen, the farmer’s servants could see the weeds. The servants came and asked, “sir, didn’t you scatter good seed in your field? Where did these weeds come from?”
“An enemy did this,” he replied.
His servants then asked, “Do you want us to go out and pull up the weeds?”
“No!” he answered. “You might also pull up the wheat. Leave the weeds alone until harvest time. Then I’ll tell my workers to gather the weeds and tie them up and burn them. But I’ll have them store the wheat in my barn.”

After Jesus left the crowd and went inside, his disciples came to him and said: “Explain to us the story about the weeds in the wheat field.” Jesus answered:
“The one who scattered the good seed is the Son of Man. The field is the world, and the good seeds are the people who belong to the kingdom. The weed seeds are those who belong to the evil one, and the one who scattered them is the devil. The harvest is the end of time, and the angels are the ones who bring in the harvest.
Weeds are gathered and burned. That’s how it will be at the end of time. The Son of Man will send out his angels, and they will gather from his kingdom everyone who does wrong or causes others to sin. Then he will throw them into a flaming furnace, where people will cry and grit their teeth in pain. But everyone who has done right will shine like the sun in their Father’s kingdom. If you have ears, pay attention!

This is a fairly straightforward message on what we need to do to enter the kingdom of heaven. Jesus is the key. If we believe in Jesus Christ (The Son of Man), partake of his body and blood in communion and ask for forgiveness of sin, we are part of the good seed. We are saved by grace, a gift from God through Jesus. Thanks be to God.

As far as what is meant by the “end of time”. My own personal belief is that it means when each of us dies. In other words, the angels are sent out at the time of our death. Others may believe differently.
