What does it mean to walk by faith according to the Bible?

Walking by faith, as exemplified by characters like Abraham, involves obeying God's commands even without full knowledge of the outcome (Hebrews 11:8). This act of obedience stems from faith—a trust in God's nature and His promises. Christians are called to live in such obedience, continually coming to Christ for sustenance, much like a baby depends on their parent. This ongoing relationship fosters spiritual growth and affirms the believer's identity as a pilgrim seeking a heavenly home, not one bound by earthly ties.
