How do we know that spiritual darkness can coexist with faith?

The concept of walking in darkness, yet being an heir of heaven, illustrates the complex spiritual journey of the believer. It is essential to understand that this darkness is not the absence of faith, but rather the experience of the believer who has tasted the light of God's grace but now feels its withdrawal. According to the text, this state of darkness is a prolonged condition that can occur even in those who genuinely fear the Lord and obey His commands. It reveals the believer's struggle with their faith, as they navigate feelings of abandonment and spiritual desolation. This struggle signifies that while they may feel lost and without light, their experiences enhance their dependence on God's grace, showcasing that true faith often exists amidst profound trials.
