God organized descendants of the patriarch Abraham into a nation and gave them a body of laws. He called the nation “Israel” and made it the custodian of true worship and of his word. (Psalm 147:19, 20) So people of all nations could benefit from Israel.​—Read Genesis 22:18.

 God chose the Israelites to be his witnesses. Their ancient history provides a demonstration of how people benefit by obeying God’s laws. (Deuteronomy 4:6) Thus, through the Israelites, others could get to know the true God.​—Read Isaiah 43:10, 12.

 In time, Israel lost God’s favor, and Jehovah replaced that nation with the Christian congregation. (Matthew 21:43; 23:37, 38) Now, in place of the Israelites, true Christians serve as Jehovah’s witnesses.​—Read Acts 15:14, 17.

 Jesus organized his followers to preach and make disciples in all nations. (Matthew 10:7, 11; 24:14; 28:19, 20) This work is reaching its climax now, in the conclusion of the present system of things. For the first time in history, Jehovah has united millions from all nations in true worship. (Revelation 7:9, 10) True Christians are organized to encourage and help one another. Worldwide, they enjoy the same program of Bible instruction at their meetings.​—Read Hebrews 10:24, 25.

 In the 1870’s a small group of Bible students began rediscovering long-lost Bible truths. They knew that Jesus had organized the Christian congregation to preach, so they began an international Kingdom-preaching campaign. In 1931 they adopted the name Jehovah’s Witnesses.​—Read Acts 1:8; 2:1, 4; 5:42.

 In the first century, the Christian congregations in many lands benefited from a central governing body that recognized Jesus as the Head of the congregation. (Acts 16:4, 5) Similarly today, Jehovah’s Witnesses worldwide benefit from a Governing Body of experienced elders. It oversees branch offices of Jehovah’s Witnesses that translate, print, and distribute Bible-study material in over 600 languages. Thus the Governing Body can provide Scriptural encouragement and direction for over 100,000 congregations worldwide. In each congregation, qualified men serve as elders, or overseers. These men lovingly care for God’s flock.​—Read 1 Peter 5:2, 3.

 Jehovah’s Witnesses are organized to preach the good news and make disciples. Like the apostles, we preach from house to house. (Acts 20:20) We also offer to study the Bible with sincere lovers of truth. But Jehovah’s Witnesses are not just an organization. We are a family with a loving Father. We are brothers and sisters who care for one another. (2 Thessalonians 1:3) Since Jehovah’s people are organized to please God and to help others, they form the happiest family on earth.​—Read Psalm 33:12; Acts 20:35.
