In the first century, perhaps the apostle who did the most to encourage his brothers was the apostle Paul. He was sent by the holy spirit to preach to the people of the nations of the Greco-Roman world, who worshipped many gods. (Gal. 2:7-9) Paul traveled far and wide in what is now Turkey, as well as in Greece and Italy, establishing Christian congregations among non-Jews. These newly converted Christians “suffered at the hands of [their] own countrymen” and needed encouragement. (1 Thess. 2:14) About the year 50 C.E., Paul wrote to the young congregation in Thessalonica: “We always thank God when we mention all of you in our prayers, for we continually remember your faithful work, your loving labor, and your endurance.” (1 Thess. 1:2, 3) He also exhorted them to strengthen one another, saying: “Keep encouraging one another and building one another up.”​—1 Thess. 5:11. w18.04 18-19 ¶16-17

Will obeying Jesus’ command to preach become burdensome? On the contrary. After relating his illustration of the vine, Jesus said that as Kingdom preachers, we will experience joy. (John 15:11) In fact, he assured us that his joy will become ours. How? Jesus compared himself to a vine and his disciples to branches. (John 15:5) A vine supports the branches. As long as the branches are attached to it, they receive water and nourishment that flows from the vine. Similarly, as long as we remain in union with Christ by closely following in his steps, we experience the same joy that he has in doing his Father’s will. (John 4:34; 17:13; 1 Pet. 2:21) Notes Hanne, a pioneer for over 40 years, “The joy I always feel after I have been in the ministry stimulates me to continue in Jehovah’s service.” Indeed, deep-seated joy gives us the strength to keep on preaching even in challenging territories.​—Matt. 5:10-12. w18.05 17 ¶2; 20 ¶14

One type of breastplate worn by a Roman soldier in the first century consisted of overlapping horizontal strips of iron. This type of garment required that he regularly check that the plates were firmly fixed in place in order to protect his heart and other vital organs. What an appropriate symbol of how Jehovah’s righteous standards can protect our figurative heart! (Prov. 4:23) Just as a soldier would not swap a breastplate of iron for one made of an inferior metal, we would never want to exchange Jehovah’s standards of what is right for our own. Our judgment is just too flawed to offer us the protection that we need. (Prov. 3:5, 6) Instead, we regularly check that the ‘iron plates’ Jehovah has given us are firmly fixed over our heart. And the more we love divine truths, the easier it is to carry our “breastplate,” that is, to live by God’s righteous standards.​—Ps. 111:7, 8; 1 John 5:3. w18.05 28 ¶3-4, 6-7

The apostle Peter had a custom of associating only with Jews. But after God made it clear that Christians should not be partial, Peter preached to Cornelius, a Roman soldier. (Acts 10:28, 35) Thereafter, Peter enjoyed food and association with Gentile believers. Years later, though, Peter stopped eating with non-Jewish Christians in the city of Antioch. (Gal. 2:11-14) In that case, Paul gave Peter a fitting reproof, which he evidently accepted. When Peter wrote his first letter to Jewish and Gentile Christians in Asia Minor, he spoke warmly about the whole association of brothers. (1 Pet. 1:1; 2:17) Clearly, the apostles did learn from Jesus’ example to love “all sorts of men.” (John 12:32; 1 Tim. 4:10) Although it took time, they adjusted their way of thinking. Putting on “the new personality,” the early Christians came to view all people as equal in the sight of God.​—Col. 3:10, 11. w18.06 11 ¶15-16

One way we let our light shine is by preaching the good news and making disciples. (Matt. 28:19, 20) In addition, we can glorify Jehovah by our Christian conduct. Householders and passersby observe our behavior. Our friendly smile and warm greeting say much about who we are and what kind of God we worship. “When you enter the house,” Jesus told his disciples, “greet the household.” (Matt. 10:12) In the area where Jesus and the apostles often preached, it was not unusual for people to invite strangers into their homes. Today, this is not the custom in many places. Still, your positive, friendly manner as you explain why you are there can often allay a householder’s concern or ease his irritation. A pleasant smile is often the best introduction. That has also proved true when brothers and sisters engage in public witnessing using a literature cart. You may find that people often react favorably to a pleasant smile and greeting. w18.06 22 ¶4-5

It makes sense to cling to Jehovah. No one is more powerful, wise, or loving than our God! Who of us would not want to be on his side? (Ps. 96:4-6) Still, some of God’s worshippers have wavered when a situation called for them to take sides with Jehovah. Consider the case of Cain. He did not profess to worship any other god but Jehovah. Cain’s worship, however, was not acceptable to God. There were seeds of wickedness growing deep within his heart. (1 John 3:12) Jehovah reached out to Cain and told him: “If you turn to doing good, will you not be restored to favor? But if you do not turn to doing good, sin is crouching at the door, and its craving is to dominate you; but will you get the mastery over it?” (Gen. 4:6, 7) Jehovah was, in effect, telling Cain, “If you repent and take a firm stand on my side, I will, in turn, be on your side.” But Cain did not listen to the counsel. w18.07 17 ¶1, 3; 18 ¶4

Our appreciation for Jehovah’s special friendship is shown in how we treat fellow worshippers. They too belong to Jehovah. If we never lose sight of that fact, we will always treat our brothers and sisters with kindness and love. (1 Thess. 5:15) Jesus said to his followers: “By this all will know that you are my disciples​—if you have love among yourselves.” (John 13:35) Interestingly, Malachi depicted Jehovah as “paying attention and listening” as His people interact with one another. (Mal. 3:16) Jehovah indeed “knows those who belong to him.” (2 Tim. 2:19) He is keenly aware of every single thing we do and say. (Heb. 4:13) When we are less than kind to our fellow worshippers, Jehovah is “paying attention and listening.” When we are hospitable, generous, forgiving, and kind to one another, we can be sure that Jehovah takes notice of that as well.​—Heb. 13:16. w18.07 26 ¶15, 17

Material wealth is a factor that can affect our view of others. But how could a person’s wealth or his poverty affect the way we view him? Holy spirit moved Solomon to record a sad truth about imperfect humans as shown in today’s text. What does this proverb teach us? If we are not careful, we could desire the friendship of brothers who are wealthy while shunning brothers who are poor. Why is it so dangerous to measure the value of others solely on the basis of their material wealth? Because doing so could create class distinctions in the congregation. The disciple James warned that this problem was dividing some congregations in the first century. (Jas. 2:1-4) We must be on guard not to allow this thinking to affect our congregation today and make sure that we fight against making judgments that are based on the outward appearance. w18.08 10 ¶8-10

Joseph was about 17 years old when his own brothers out of jealousy sold him as a slave. Prior to this, Joseph had been his father’s favorite. (Gen. 37:2-4, 23-28) For about 13 years, Joseph had to endure slavery and imprisonment in Egypt, far away from his beloved father, Jacob. What helped Joseph not to give in to despair and bitterness? While suffering in prison, Joseph must have focused his mind on evidence of Jehovah’s blessing. (Gen. 39:21; Ps. 105:17-19) The prophetic dreams that Joseph had when he was younger would also have given him confidence that he had Jehovah’s favor. (Gen. 37:5-11) He likely poured out his anguish to Jehovah on more than one occasion. (Ps. 145:18) In response to Joseph’s heartfelt prayers, Jehovah gave him the inner conviction that He would be “with him” in all his trials. w18.10 28 ¶3-4

Jehovah expects his servants to care for their families. For example, you may have to work to provide financially for your loved ones. Many mothers stay at home to look after their infants. And some adult children may have to care for infirm parents. These are necessary activities. If you have such responsibilities, you likely cannot set aside as much time for theocratic activities as you would like to. But take heart! Jehovah is pleased when you provide for your family. (1 Cor. 10:31) If you do not have pressing family responsibilities, could you assist fellow worshippers who are caregivers and those who are infirm, elderly, or otherwise in need? Why not look around in your congregation and take note of who needs help? In doing so, you might be working with Jehovah to answer a prayer.​—1 Cor. 10:24. w18.08 24 ¶3, 5
