Seeing what is invisible

This sermon explores the theological definition of faith as the substance and evidence of things not seen, using the siege of Jericho in Joshua 6 as a primary illustration. It contrasts the physical reality of fortified walls and closed gates with the spiritual reality of God's past-tense promise that the city has already been given to Joshua. The message emphasizes that biblical faith is not blind optimism or the denial of present circumstances, but a clear-sighted trust in the unchanging character of God and the eternal nature of His promises over the temporal nature of visible reality. This trust in the unseen foundation leads to steady, enduring obedience, exemplified by Joshua's unconventional march around the city. Ultimately, the sermon points to Jesus Christ as the greater Joshua, whose finished work on the cross provides the ultimate basis for the believer's confidence, righteousness, and hope in the face of life's obstacles.
