The Bible contains many prophecies that were fulfilled, some of them hundreds of years after they were recorded. History confirms that these prophecies came true. This does not surprise us because we know that the Author of Bible prophecy is Jehovah. Think of the prophecies regarding the fall of the ancient city of Babylon. In the eighth century B.C.E., the prophet Isaiah was inspired to foretell that the then powerful city of Babylon would be captured. He even gave the name of its conqueror, Cyrus, and foretold precisely how the city would be seized. (Isa. 44:27–45:2) Isaiah also prophesied that Babylon would eventually be destroyed and completely deserted. (Isa. 13:19, 20) Babylon fell to the Medes and the Persians in 539 B.C.E., and the site of this once great city is now a pile of ruins. w23.01 4 ¶10

Jehovah has chosen us to be part of his worldwide family of worshippers. Just think what a privilege that is and what benefits it brings! (Mark 10:29, 30) Around the world, we have brothers and sisters who share our love for Jehovah and who try their best to live by his standards. Our language, culture, and dress may be different from theirs, but we feel close to them, even when meeting them for the first time. We especially love to be with them to praise and worship our loving heavenly Father, and we need to remain united with them. (Ps. 133:1) At times, they help us to carry our burdens. (Rom. 15:1; Gal. 6:2) They also encourage us to stay active in Jehovah’s service and to keep spiritually strong. (Heb. 10:23-25) Think how we would feel if we did not have the protection of the congregation to help us stand firm against our common enemies​—Satan the Devil and his wicked world. w22.09 2-3 ¶3-4

We may find that our self-control is put to the test when we are using social media. If not careful, we could unintentionally reveal confidential matters to a large audience. And once we broadcast the information electronically, we have no control over how it will be used or how much damage it will cause. Self-control also allows us to remain silent when opposers try to trick us into revealing things that could endanger our brothers and sisters. This might occur when we are being interrogated by the police in a land where our work is banned or restricted. We can apply the principle to “guard [our] mouth with a muzzle” in these and other situations as well. (Ps. 39:1) Whether we are dealing with our family, our friends, our brothers and sisters, or anyone else, we need to be trustworthy. And to be trustworthy, we need self-control. w22.09 13 ¶16
