What duty do Christians owe one another according to the principles stated?

The correct response emphasizes that Christians are called to embody love in both their words and actions toward one another. This principle is deeply rooted in biblical teachings, particularly the command to "love your neighbor as yourself." This love is not merely a feeling but manifests through acts of kindness, support, and service.

In practice, this means promoting unity within the body of Christ and fostering a supportive community where individuals care for one another's needs—spiritually, emotionally, and physically. By demonstrating love in tangible ways, Christians reflect the character of Christ and fulfill their obligations to one another as members of the same faith family.

This understanding of love contrasts sharply with competitive or self-serving behaviors. Competing against one another undermines the communal spirit and can lead to division rather than harmony. Similarly, avoiding theological discussions does not promote growth or understanding within the community, and prioritizing personal interests goes against the call to serve others sacrificially. Each of these other options fails to capture the essence of mutual support and care that love entails.
