Christians should regularly reflect on what they see and experience to better help others.
Keeping an active mind about what is happening around oneself helps a Christian gain insight into how to help people when others may not even really recognize what the current problem is.
One valuable trait that should be part of a Christian life is cultivating an active mind that regularly assesses and reassesses what is being seen and experienced in order to gain insight into how to help others. Consider a workplace where the authority of supervisors has been considerably decreased after some particularly controlling supervisors caused significant problems; a year later, however, employees are barely listening to their new supervisors, they aren't following basic procedures, and they are even teasing their supervisors when they try to enforce basic policies. A Christian employee here would want to recognize that although the domineering behaviors of some supervisors from the past were not appropriate, the way the new supervisors were now being treated was not appropriate either and that they should try to communicate to company HQ what was going on.
That scenario represents many different kinds of problems in society today where a proposed solution causes another problem that may be as bad or worse in different ways. It takes an active mind to think about how a current solution may be hurting people. This can involve challenging the ideas of a whole company or large sectors of a public, but individuals can do that and it has been done successfully more than a few times.
The teachings of Christianity call Christians to be a help to people. Keeping an active mind about what is happening around oneself helps a Christian gain insight into how to help people when others may not even really recognize what the current problem is. This insight is valuable for both Christians and non-Christians alike in bettering public life.
