Jehovah’s Witnesses believe that:
- The extent to which one engages in the house-to-house preaching activity determines to a large degree his standing before Jehovah 
- All JWs are required to spend time regularly in the preaching work 
- The message to be preached today is that the kingdom of God, established in 1914, is the only hope of eternal life on the paradise earth 
Mainstream Christianity believe they have given a far larger scale witness and seen many times the growth of Jehovah’s Witnesses
Q1. Are Christians encouraged to witness to their fellow men?
Answer: all believers are called to bear witness to the truth of Jesus Christ.
Matt 28:19-20 “Go therefore and make disciples of all nations … teaching them to observe all that I have commanded you.”
Acts 1:8 “You will be my witnesses in Jerusalem and in all Judea and Samaria, and to the end of the earth.”
Rom 10:14 How are they to believe in him of whom they have never heard? And how are they to hear without someone preaching?
1 Cor 9:16 Necessity is laid upon me. Woe to me if I do not preach the gospel!
2 Cor 5:18 God, who through Christ reconciled us to himself and gave us the ministry of reconciliation
1 Pet 3:15 In your hearts honour Christ the Lord as holy, always being prepared to make a defence to anyone who asks you for a reason for the hope that is in you
Rev 22:17 Let the one who hears say, “Come.”
(Also, Acts 5:42; 10:42; 20:20; 1 Cor 11:1; Eph 6:15; Phil 1:14; 2 Tim 4:2)
Q2. Is house-to-house preaching a prerequisite for salvation?
Answer: No. Did Jesus preach before his baptism? Did Zacchaeus, the robber hanging next to Christ, the Ethiopian eunuch, Cornelius or the Philippian jailer need to qualify as “unbaptized publishers” and turn in reports before they were saved?
- Scripture Explainer ‘Acts 20:20’;
- FAQ ‘We are the only religion that preaches worldwide.’]
Luke 19:8-9 Zacchaeus stood and said to the Lord, “Behold, Lord, half of my goods I give to the poor… Jesus said to him, “Today salvation has come to this house.”
Luke 23:42-43 “Jesus, remember me when you come into your kingdom.” And he said to him [the robber], “Truly, I say to you, today you will be with me in Paradise.”
Acts 8:36-38 He commanded the chariot to stop, and they both went down into the water, Philip and the eunuch, and he baptized him.
Acts 16:30-33 “Sirs, what must I do to be saved?” And they said, “Believe in the Lord Jesus, and you will be saved, you and your household.” … he [jailer] was baptized at once, he and all his family.
Q3. Do Christians all have identical roles in the ministry?
Answer: All Christians can bear witness by holy living and personal testimony; some though have the role of evangelizers explaining the message of Christ and salvation, but there are a great variety of God appointed roles.
Rom 12:4-6 For as in one body we have many members, and the members do not all have the same function, so we, though many, are one body in Christ, and individually members one of another. Having gifts that differ according to the grace given to us, let us use them
1 Cor 12:28-29 God has appointed in the church first apostles, second prophets, third teachers, then miracles, then gifts of healing, helping, administrating, and various kinds of tongues. Are all apostles? Are all prophets? Are all teachers?
(Also, Eph 4:11-13)
Q4. What message is to be preached by Christians today? How?
Answer: See ‘The Gospel’ and Scripture Explainer ‘Matt 24:14’
Acts 10:42 He commanded us to preach to the people and to testify that he is the one appointed by God to be judge of the living and the dead.
Luke 24:45-48 He [Jesus] opened their minds to understand the Scriptures, and said to them, “Thus it is written, that the Christ should suffer and on the third day rise from the dead, and that repentance and forgiveness of sins should be proclaimed in his name to all nations …
