By 1979, Harriet E. Miers, then in her mid-30's, had accomplished what some people take a lifetime to achieve. She was a partner at Locke Purnell Boren Laney & Neely, one of the most prestigious law firms in the South, with an office on the 35th floor of the Republic National Bank Tower in downtown Dallas.

But she still felt something was missing in her life, and it was after a series of long discussions - rambling conversations about family and religion and other matters that typically stretched from early evening into the night - with Nathan L. Hecht, a junior colleague at the law firm, that she made a decision that many of the people around her say changed her life.

"She decided that she wanted faith to be a bigger part of her life," Justice Hecht, who now serves on the Texas Supreme Court, said in an interview. "One evening she called me to her office and said she was ready to make a commitment" to accept Jesus Christ as her savior and be born again, he said. He walked down the hallway from his office to hers, and there amid the legal briefs and court papers, Ms. Miers and Justice Hecht "prayed and talked," he said.

She was baptized not long after that, at the Valley View Christian Church.

It was a pivotal personal transformation for the woman now named for a seat on the United States Supreme Court, not entirely unlike that experienced by President Bush and others in the Texas political and business establishment of that time.
