How do we know that external religious practices are insufficient?

The teachings of Horatius Bonar remind us that while external religious practices, such as ceremonies or music, may provide temporary comfort (as shown in 1 Samuel 16:23), they do not sufficiently address the core issues of sin and separation from God. These practices can lead to a false sense of security, as they only mask the soul's emptiness. True redemption and healing come not from human contrivances but from a personal relationship with Jesus Christ, who offers true solace and sanctification. Thus, an understanding of our need for God’s remedy, rather than man's, is crucial for genuine spiritual restoration.
