Jesus Told The Disciple Teice to Cast their Nets

When I was searching john 21:22 I found out that Jesus told the disciples to cast their nets 

But back to John 21:22....I had written down a quote by CS Lewis from Mere Christianity in my journal but it stuck with me. 

I've to mind my own business and stop looking at others mistakes. It's up to Jesus how he judges others and what happens to them
