Jesus compares the kingdom of heaven to a net cast into the sea, gathering fish of every kind. This parable teaches us that the gospel must be actively shared outside church walls to reach people from all backgrounds. The Holy Spirit guides our evangelistic efforts, showing us who is receptive to the message. Eventually, there will be a separation between those who accept and reject the gospel, highlighting the urgency of sharing our faith. Christians are called to think outwardly rather than inwardly, using practical methods like prayer walks, hospitality, and intentional conversations to connect with others.
