Fish Net and New Wine

Before the resurrection (Luke 5:4-5, KJV)
     at Jesus' call of the disciples
         -- they had fished all night and didn't catch anything
         --Jesus said to let down the net
         --caught so many fish, the net broke

After the resurrection (John 21:6-8)
         --fished all night and didn't catch anything
         --Jesus said to cast the net on the right side
         --caught many big fish, but the net didn't break

These stories remind me of the parable of the new wine in old bottles (Matthew 9:16-17).
The new wine answers to the Holy Spirit working in the men that are being fished for, but the net, just like the old covenant, just isn't sufficient to save men.  After the resurrection, the disciples are able to save fish (men) because the net (new covenant) doesn't break.

Each time, they obeyed Jesus even though it looked like a waste of time.  Jesus is able to use Christians to be fishers of men if they obey Him.
