The convert who does not join a church is likely soon to be in a bad way; so Sunday early united with the Jefferson Park Presbyterian Church, Chicago. He went into religious activity with all the ardor that he displayed on the baseball field. He attended the Christian Endeavor society, prayer-meeting and the mid-week church service. This is significant; for it is usually the church members who are faithful at the mid-week prayer-meetings who are the vital force in a congregation. Other rewards than spiritual awaited Sunday at the prayer-meeting; for there he met Helen A. Thompson, the young woman who subsequently became his wife. Between the meeting and the marriage altar there were various obstacles to be overcome. Another suitor was in the way, and besides, Miss Thompson's father did not take kindly to the idea of a professional baseball player as a possible son-in-law, for he had old-fashioned Scotch notions of things. "Love conquers all," and in September, 1888, the young couple were married, taking their wedding trip by going on circuit with the baseball team. Mrs. Sunday's influence upon her husband has been extraordinary. It is a factor to be largely considered in any estimate of the man. He is a devoted husband, of the American type, and with his ardent loyalty to his wife has complete confidence in her judgment. She is his man of affairs. Her Scotch heritage has endowed her with the prudent qualities of that race, and she is the business manager of Mr. Sunday's campaigns. She it is who holds her generous, careless husband down to a realization of the practicalities of life. He makes no important decisions without consulting her, and she travels with him nearly all of the time, attending his meetings and watching over his work and his personal well-being like a mother. In addition Mrs. Sunday does yeoman service in the evangelistic campaigns. The helplessness of the evangelist without his wife is almost ludicrous: he dislikes to settle any question, whether it be an acceptance of an invitation from a city or the employment of an additional worker, without Mrs. Sunday's counsel. Frequently he turns vexed problems over to her, and abides implicitly by her decision, without looking into the matter himself at all. Four children--Helen, George, William and Paul--have been born to the Sundays, two of whom are themselves married. The modest Sunday home is in Winona Lake, Indiana. When Mrs. Sunday is absent with her husband, the two younger children are left in the care of a trusted helper. The evangelist himself is home for only a short period each summer.
