Jacob did not have an easy life. He had to put up with his fleshly-minded brother, Esau, who intended to kill him. On top of that, he had to deal with a deceitful father-in-law, who repeatedly tried to exploit him. Yet, despite being surrounded by “physical” men, Jacob was a spiritual man. (1 Cor. 2:14-16) He had faith in the promise made to Abraham and devoted himself to caring for the family who would play a special role in the outworking of Jehovah’s purpose. (Gen. 28:10-15) Jacob’s words and actions reveal that he had God’s standards and will in mind. For example, when he felt threatened by Esau, Jacob said to God: “Save me, I pray you . . . You have said: ‘I will certainly deal well with you, and I will make your offspring like the grains of sand of the sea.’” (Gen. 32:6-12) He obviously put faith in Jehovah’s promises and wanted to act in harmony with God’s will and purpose. w18.02 20 ¶9-10

Consider the example of a Jewish man who was persecuting Christians. He was born in a nation that was dedicated to God. However, the Jews had lost their special relationship with Jehovah. That man was zealous for the traditions of Judaism, but he learned a better way. He received a personal witness from the resurrected and glorified Jesus Christ. What was the man’s response? He welcomed assistance from the Christian disciple Ananias. Regarding that man the Bible tells us: “He then got up and was baptized.” (Acts 9:17, 18; Gal. 1:14) You certainly recognize that Jewish man as the one who came to be known as the apostle Paul. But reflect on the fact that once he gained appreciation for the truth about Jesus’ role in the outworking of God’s purpose, Paul acted. He got baptized without delay. (Acts 22:12-16) It is much the same with Bible students today, whether young or old. w18.03 5-6 ¶9-11

The Bible speaks highly of spiritually-minded people. Romans 8:6 shows the advantage of being spiritually-minded, saying: “Setting the mind on the flesh means death, but setting the mind on the spirit means life and peace.” By focusing on spiritual things, we gain peace with God and with ourselves now and the prospect of everlasting life in the future. However, we live in a dangerous environment. Since fleshly attitudes are all around us, we need to put forth real effort to develop spirituality and to guard it once we have it. If a person loses his spirituality, he creates a moral vacuum and the polluted “air” of this world will rush in. Jude spoke of those who would deteriorate even to the point of “not having spirituality.”​—Jude 18, 19. w18.02 19 ¶5, 7; 20 ¶8

We welcome all who attend our Christian meetings as fellow guests at a spiritual meal. Jehovah and his organization are our hosts. (Rom. 15:7) When new ones attend, we become cohosts, as it were. Why not take the initiative to welcome these new ones, no matter how they may be dressed or groomed? (Jas. 2:1-4) If a visitor is not already being cared for, could you invite him to sit with you? He might appreciate help to follow the program and perhaps to find scriptures being read. This would be a fine way to “follow the course of hospitality.” Visits of public speakers from other congregations, as well as visits of circuit overseers and, at times, representatives from the local branch office, provide opportunities for us to extend hospitality. (3 John 5-8) Providing refreshments or a meal is one fine way of doing this. Could you assist? w18.03 15 ¶5, 7

Self-discipline includes exercising control over ourselves in order to improve in our behavior and thinking. We are not born with an inclination toward self-discipline. We have to learn it. When parents consistently and patiently train their little ones “in the discipline and admonition of Jehovah,” they are also helping their children to develop self-discipline and wisdom. (Eph. 6:4) The same principles apply to those who come to know Jehovah as adults. True, they may already have developed a measure of self-discipline. Spiritually speaking, however, a new disciple starts off being immature. But he or she can steadily grow toward maturity as part of learning to put on the Christlike “new personality.” (Eph. 4:23, 24) Self-discipline is an important part of that growth. w18.03 29 ¶3-4
