If we are patient with people in the ministry, we will not expect them to understand or accept Bible truth the first time they hear it. As an example, consider how we might reason with someone about the hope of everlasting life on a paradise earth. Many believe that death is the end of it all or that all good people go to heaven. One brother relates an approach that he finds effective. First, he reads Genesis 1:28. Then, he asks the householder where and in what conditions God wanted the human family to live. Most people answer, “On earth, in good conditions.” Next, the brother reads Isaiah 55:11 and asks whether God’s purpose has changed. Often, the householder will answer no. Finally, the brother reads Psalm 37:10, 11 and asks what mankind’s future will be like. Using this Scriptural reasoning, he has helped a number of people to understand that God still wants good people to live forever in Paradise on earth. w19.03 24 ¶14-15; 25 ¶19

Even though Adam and Eve initially enjoyed freedom in many ways, there were limits imposed on them. Some of them were instinctive, but they were limits nonetheless. For example, our first parents knew that to keep on living, they had to breathe, eat, sleep, and so on. Would they feel a loss of freedom for having to do these things? No, for Jehovah saw to it that even in doing such routine things, they could find enjoyment and contentment. (Ps. 104:14, 15; Eccl. 3:12, 13) Jehovah specifically commanded Adam and Eve to populate the earth and to take care of it. Did this command in some way deprive them of their freedom? Of course not! It was given to enable humans to participate in their Creator’s purpose​—to make the earth into a global paradise home for a race of perfect humans forever. (Ps. 127:3; Isa. 45:18) Enjoying their marriage and family for all eternity could have been Adam and Eve’s happy lot in life. w18.04 4-5 ¶7-8

A young person who focuses his life on the desire to please Jehovah gives special attention to the ministry. Because the preaching work is so urgent, it should be high on our list of priorities. Could you set the goal of sharing in the ministry more often? Could you pioneer? But what if you find little joy in preaching? And how can you be more effective at giving a witness? Two basic steps will help: Prepare well, and do not give up sharing what you know with others. It might surprise you how much joy you will then find when preaching. You could start by working out an answer to a question commonly raised by schoolmates, such as “Why do you believe in God?” Our jw.org website contains articles designed to help young people work out for themselves how to answer that question. There you will find a worksheet entitled “Why Do I Believe in God?” The worksheet will guide you in preparing your own answer. w18.04 27 ¶10-11

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
