“Again, the kingdom of heaven is like a dragnet that was cast into the sea and gathered some of every kind, which, when it was full, they drew to shore; and they sat down and gathered the good into vessels, but threw the bad away” (Matthew 13:47-48 NKJV).

I don’t know what you believe about heaven and hell, but Jesus taught that they were real places of eternal existence. In this parable of Jesus, He compared the kingdom of heaven to a fishing net that caught both good and bad fish. The good fish represented those who truly believed in Christ as Lord. And the bad represented those who were hypocrites.
The kingdom of heaven is to be populated by those who have made Christ king. However, there are those who pay lip service to Jesus outwardly, yet inwardly their hearts remain unchanged. They still have “self” on the throne. They have not made Christ the Lord of their lives. They are hypocrites. As the gospel “dragnet” gathers people into the church, both the saved and the hypocrite are present. Yet, at the “end of the age” (Matt.13:49), they will be separated. The “just” to everlasting life and the “wicked” to a place of everlasting torment called Hell.
This is why we must continually preach the gospel to the church. For we do not know who there is among us that has yet to truly confess Christ as King. And this is why each of us must examine our own hearts to be sure that we have truly submitted our lives to Jesus. Have you confessed Jesus as Lord and believed that God raised Him from the dead? Are you truly among the redeemed? The end of the age is coming. Are you ready?
