Paul wrote: “Really, woe is me if I did not declare the good news!” (1 Corinthians 9:16) He was not casual about the good news because preaching it meant life for himself and his hearers. (1 Timothy 4:16) We view our ministry in the same way. We want to help our neighbors. We want to show our love for Jehovah. We want to prove our love for Jesus and our appreciation for his great love for us. Hence, we preach the good news and thus live “no more for the desires of men, but for God’s will.”—1 Peter 4:1,2.
If they truely want to help their neighbors with a thorough witness why stick with the "tried and failed" methods they use, why not night field service when people are ACTUALLY home...
