This sermon explores the biblical definition of faith as the substance of things hoped for and the evidence of things not seen, using Hebrews 11 as the primary text. It outlines eight distinct aspects of faith, including its ability to perceive the invisible, believe the impossible, seek miracles, obey the unthinkable, desire the incorruptible, refuse the irresistible, conquer the undefeatable, and endure the unbearable. Through examples such as Abel, Noah, Abraham, Moses, and the prophets, the message illustrates how faith operates in creation, redemption, and daily obedience. The tone is instructional and encouraging, emphasizing that while these feats seem impossible to human logic, they are achievable through trust in God's Word. The sermon concludes by directing the audience to look unto Jesus, the author and finisher of faith, as the source of strength to run the race of life with patience and endurance.
