Iglesia ni Cristo strongly affirms James 2:24 that faith without works is dead. Genuine faith in God must be demonstrated through obedience, moral behavior, and active charity. The church teaches that belief alone without corresponding works of obedience is not saving faith. Works are not viewed as earning salvation but as the inevitable fruit and evidence of genuine faith.

This conviction shapes Iglesia ni Cristo's emphasis on moral living, strict ethical conduct, and active service within the church community. Believers are expected to demonstrate their faith through obedient action and moral transformation.
