A.W. Tozer emphasizes that faith must be demonstrated rather than merely defined, drawing from the examples of faith in Hebrews 11. He asserts that both preachers and congregants are called to actively show their faith through their actions and lives, reflecting God's love and ideals. Tozer encourages believers to lay aside distractions and sins, running the race of faith with endurance, and to seek the Holy Spirit's strength to embody this unwavering faith.
