Moravians affirm James 2:24 as teaching that faith without works is dead. Zinzendorf emphasized that faith in Christ's love (especially Christ's suffering and redemption) necessarily produces active love and service. Works are not a means to salvation but evidence of the Holy Spirit's work in the believer's life.

The Moravian tradition emphasizes the 'heart religion': genuine faith transforms the heart, producing love for God and love for neighbor. This love works out in practical service, mutual aid, and missions. The Moravians were pioneers in missionary work and community living based on this principle. James's teaching reflects the Moravian conviction that true Christianity is faith in Christ expressing itself through active, self-giving love.
