Jesus teaches his disciples to properly use a net to catch men. They must (1) wash the net in the word of God and through tears of repentance for lost souls, (2) mend any holes in the net by correcting doctrinal errors, and (3) move the net to new preaching locations under the guidance of the Holy Spirit. Effective witnessing requires preparation through studying the Bible, interceding for the lost, addressing false teachings, and going where God leads to spread the gospel message.
