What does the Bible say about looking at things not seen?

In 2 Corinthians 4:18, the apostle Paul instructs believers to shift their focus from the seen to the unseen. This principle is rooted in the understanding that the current life is fleeting and filled with trials, while the eternal promises of God are sure and substantial. Old Testament believers illustrated this by having faith in distant promises, allowing them to experience joy and hope regardless of their earthly circumstances. Such faith acts like a lens, magnifying the glorious blessings that await us beyond this life.
