What does the Bible say about the gospel net?

In Matthew 13:47-50, Jesus describes the kingdom of heaven as a net cast into the sea, which gathers fish of every kind. This parable illustrates how the gospel serves as a means appointed by God to gather His elect, the 'good fish.' Just like fishermen sort out the catch, the Lord will ultimately separate the wicked from the just at the end of the world. This emphasizes the responsibility of believers to preach the gospel, as it pleases God to call His people through preaching and to gather them into His fold. Salvation is not a mere possibility but is accomplished definitively through Christ for those selected by God in His sovereignty.
