According to James, faith must be practiced with works. This means that faith is not just about believing in something, but it must also be accompanied by action. James believed that faith without works is dead, meaning that if one has faith but does not show it through action, then it is not genuine faith. Therefore, James emphasized the importance of not just believing in God, but also putting that belief into practice by doing good works and helping others. In summary, James believed that true faith involves both belief and action, and that these two aspects cannot be separated.
