The Church evangelizes the lost primarily through the preaching of the Word (see part 1). The church also evangelizes the lost by equipping the saints to do the work of the ministry (Ephesians 4:11-12). The work of the ministry includes the exercising of each one's gifts within the body, but it also includes the hard work of sowing the seed. Everyone should participate in evangelizing the lost, even the elders (2 Timothy 4:5).
Although there is nothing wrong with a banquet or a program, these activities tend to relieve people of their responsibility to sow the seed of the Gospel to the lost. Jesus tells us in the parable of the Great Supper, to go into the highways and byways and compel people to come (Luke 14:15-24). The reality is, we would prefer to serve in a kitchen than cast the seed of the Gospel to the lost.
The parable of the soil teaches us that many will reject the Gospel. In fact, three of the four soils produced no fruit. I interpret that to mean that those people did not turn to Christ as their Savior and Lord. They sprouted, but they never demonstrated continued faith. Don't let this discourage you. Your responsibility is to sow the seed. God produces the faith.
