According to Myers-Briggs, ISFJs are interested in maintaining harmony in every aspect of their lives. They best understand and response to that which is concrete and can allow them to maintain order. They are genuinely warm and considerate people who find it easy to see Christ in their interactions with others. They believe the best in everyone and they their kind-hearted nature is a reflection of their sensitivity to the feelings of others. Although quiet, they are people-oriented and very observant. Not only do they remember details about others, but they observe and respect the feelings and desires of others.
An ISFJ's keen awareness of the feelings of others is counterbalanced by their awareness of their own feelings. They may not express these feelings, but they are constantly processing their observations of the people and world around them and reflecting about them in their own lives. This is in part made possible by an ISFJ's accurate memory, one of their strongest gifts. Their memory combined with their sensitivity to the feelings of others make them very gifted in serving to some of the most personal needs of individuals. It is not uncommon for people to get the feeling that an ISFJ knows them better than they know themselves.
ISFJs have a strong set of values that factor into how they frame the world around them. They tend to have very concrete visions of how things should be and they will do their best to make their lives reflect that. They value tradition and respect systems and are comforted by security and the kindness of others. As long as the world around them achieves those goals, they will likely be suspicious to change unless they perceive it to be extremely necessary. Part of this is due to their SJ (Sensing-Judging) temperament, which places a high value on order and respect elders and ritual. This is often true of an ISFJ's faith life.
ISFJs are doers who prefer a hands on approach to learning, as opposed to distant examination or having someone explain a concept theoretically. They shy away from roles than involve heavy analysis and will gravitate towards callings that deal with the practical and concrete. Once they learn and understand their task within a ministry, the rest is history. They are steadfast and meticulous in handling their responsibilities. They will do the most routine and often undesirable work in a ministry as long as they find purpose and value in what they are doing. Friends and family are likely to describe them as thoughtful and trustworthy. ISFJs take the idea of responsibility very seriously and will often become an individual that many people rely on because an ISFJ can be reluctant to tell a person in need "no." Because of this, they can often become overwhelmed with responsibility, but will bottle their stress or frustrations rather than burden those around them. An ISFJ can avoid being taken for granted by expressing their own feelings in lieu of the risk of conflict with others. People can support an ISFJ by verbally expressing their appreciation for their gifts.
