The virus that was caught in the tissue represents those who are embarrassed to spread the message about the Kingdom. Then the evil one comes and snatches away the message meant for others. The person who caught the virus but suppressed the symptoms represents those who hear the message, immediately receive, but then resist and walk away. Since the virus doesn’t take hold they don’t display the symptoms of the Kingdom. The people who were immune to the virus had heard about the Kingdom before but didn’t believe its message could provide answers to the worries of this life and preferred the lure of wealth, so again no fruit of the Kingdom is produced. The virus that infected other people represents those who truly hear and understand God’s word through the pain, suffering and weakness of an individual and spreads like an outbreak producing Kingdom symptoms thirty, sixty, or even a hundred times as much as the index case!
Matthew 13 v3-9, 19-23
The Kingdom of God is like a man who was infected with a virus and was sneezing.
Once or twice as he sneezed he caught the virus in a tissue and threw it away in the bin.
Other virus particles infected his neighbour, who took regular paracetamol and ibuprofen and did not develop symptoms.
He sneezed on people who had already had the same cold and their immune system choked out the virus.
But he kept sneezing and some virus particles fell on those not immune to it, and it produced viral symptoms that were thirty, sixty, and even a hundred times as much as the man had!
Anyone with ears to hear should listen and understand.
