When 15-year-old Christy McGill traveled cross country for basketball camp, her father, Jack, pushed aside paperwork, cancelled Bible studies and postponed meetings to accompany her and to help coach the teen-age girls. "Jack is a coach by nature," says his wife, Sheri. "It's just such a part of his personality."

That personality spills over into his job as director of Priority Associates, Campus Crusade for Christ's ministry to business professionals. Just as a basketball coach guides the players, so Jack leads businessmen and women to view the marketplace as a mission field.

Last year he kept his hands involved hosting presidents of companies, owners of insurance agencies and other Orlando business leaders. "These men have great influence," Jack says. "Some are in charge of 50 to 70 people or more." The group met from 7 to 8:15 a.m. every Tuesday for six weeks at the long, wooden table in the Priority Associates conference room. Jack led them through Developing the Leader Within You by John Maxwell, sprinkling in Bible verses as applicable.

A key element of Jack's coaching strategy involves a core group of seven men he leads in a discipleship group twice a month. He's been coaching these men, or "players," as he calls them, for the past 11 years. These guys know the game and can lead others to faith in Christ. Through them Jack puts his strategy to work.

A few years ago, Gregg invited co-worker Charles Knight to an evangelistic luncheon where Adolph Coors IV spoke about success. On a comment card the co-worker indicated a desire to learn more about Jesus. After reading his response, Jack encouraged Gregg to meet Charles. So they met for lunch. Jack came along, and, coaching by example, explained the Four Spiritual Laws to Charles, who readily accepted Jesus as his Savior.

Gregg now presents Christ to all of his employees. Charles serves as an elder in his church, and he, too, shows others how to start and develop a personal relationship with God. He helped lead his associate and friend Eric Duncan to the Lord, who in turn, introduced his friend Michael Gahan to Christ. All of these men go out of their way to make Christ known and to develop spiritual leaders among their friends and co-workers.

"[Jack] is able to come into the white-collar world and become one of us," says Glenn Repple, a financial consultant involved in Jack's discipleship group. "With his talents he could be earning a lot more money."

But a pile of money is not what Jack wants. Instead, he prays for Priority Associates to penetrate America's 100 largest cities. And God is blessing his efforts--in the past three years, the Priority staff team has grown from 40 full-time staff to 65 in 12 U.S. cities.

Jack's coaching doesn't stop when he leaves the office. "He's never put his ministry above our family," Sheri says. She met her husband while working as a Campus Crusade staff member at the University of Georgia; Jack helped lead the ministry at Auburn. They married 17 years ago and have three children: Christy, Brady and Heather.

Jack's office dry-erase board constantly reminds him of his two daughters. In one corner his nine-year-old etched the words: "I love you Daddy. Love Heather, your daughter." The other side reads, "Hello Jack McGill. I love you. Have a great day. Love always, Christy #21" next to a drawing of a basketball. "I make everyone write around [those]," Jack declares. And they do. Charts and scribble clutter the board, but his daughters' art remains.

Sunday afternoons he coaches a different member of his home team, 12-year-old Brady. The father and son go to McDonald's and study a workbook (Teknon and the Champion Warriors, by Jack and Sheri's friend Brent Sapp) designed for fathers to teach their sons godly principles. Sheri added her ideas to the manuscript, which will be published in February. When Brady and Jack complete the workbook next summer, Jack plans on taking Brady canoeing and camping in Colorado's Rocky Mountain National Park as an initiation into young manhood. "He's trying to impart special father-daughter, father-son memories," says Sheri.

"Sometimes I struggle with the fear of failure," admits Jack, paradoxically. He leans forward in his swivel chair and adds, "I constantly have to go back to who God is and my call to be involved in people's lives." To remember his call, Jack reminds himself of the mission statement he wrote for his life: "To love and follow Christ wholeheartedly, to lead others to and in Christ faithfully, and to leave a legacy for Christ eternally."

Reasoning that Christ most influenced His disciples by spending time with them, he has developed the conviction that if at all possible, he will never do anything alone, but rather with a member of his family or one of his disciples.

Knowing God motivates Jack. "I have to know in my heart and soul and deep down--that I'm for real," declares Jack. "I have to know that God is real in my life and He is not my occupation, but He's my love and passion."

To make sure he's living up to God's call, Jack sets aside three to five days each year to refocus. He spends the time alone at the beach, praying, fasting and asking God to speak to him about the upcoming year. "It takes a lot of discipline because Jack hates to be by himself," says Sheri, "yet he sees the value of pulling away--retreating like Jesus did--and listening to Him and stripping away everything that can cause him not to hear God's voice."
