El autor presenta un caso breve pero persuasivo a favor de la necesidad de casarse sólo en el Señor. Su manera de abordar el tema es realista, simpática, y bíblica. Tomando 1ª a los Corintios 6:20, 7:23 como punto de partida, él discute la regla bíblica básica y sus implicaciones, y luego ofrece razones que apoyan su caso, 2 negativas y 3 positivas, arraigadas en principios bíblicos generales. Concluye con testimonios, consejos para los que ya se encuentran casados con incrédulos, y sugerencias para hallar un compañero matrimonial.

Marriage, claims Andrew Swanson, is 'one of the most important questions you will ever think about. In "Whom Shall I Marry?" he underlines the most important principles which Scripture gives in order to guide us to a wise and happy choice of a life-long partner. These principles are plain and clear. But they are not always easy to put into practice.

Andrew Swanson writes with sensitivity to the struggles and difficulties which young people from various cultures face in this area of life. Convinced that God's promise, 'them that honor me I will honor' holds good today, he writes both realistically and encouragingly about the ways in which God guides and directs those whose central desire is to do his will.
