Mark 1:21-28 – The Authority of Jesus: Then and Now.

My Bible study notes for Wednesday night, January 28. Remember, these are my personal study notes and not a manuscript of the sermon. They are provided as an outline each week for our Tabernacle Church family. You can find Sermon Notes, Family Devotional Guides, Prayer List, and other resources at our Church Website.


Mark 1:21–28

Authority Begins with God’s Word – vv. 21–22

  • Jesus enters the synagogue—where the Word should have been central.
  • He teaches with authority rooted in Scripture, not tradition or opinion.
  • God’s Word, spoken clearly and faithfully, is sufficient.
  • The people are astonished—overwhelmed, shaken in mind and heart.
    • Not impressed by style, but confronted by truth.

Light (truth) Exposes What Is Hidden – vv. 23–26

  • The presence of the Word exposes darkness (John 3:19–21).
  • An unclean spirit is revealed in a religious setting.
    • Religion ≠ regeneration.
  • Evil does not debate Jesus—it submits.
  • Biblical evangelism:
    • No coercion
    • No gimmicks
    • No manipulation
    • Let the Word do the work

Amazement Follows a Life Changed – vv. 27–28

  • The crowd marvels at both His teaching and His power.
  • The focus remains on who Jesus is, not what people can do.
  • True amazement points outward—to Christ’s authority, not human ability.

THE WHAT NOW

Our Authority Today

  • We speak with Christ’s authority, not our own (Matt. 28:18–20).
  • The Word of God carries power—not personality, position, or volume (Heb. 4:12).
  • Spiritual authority flows from submission to Christ (James 4:7–10).
  • The gospel confronts darkness—truth exposes error and sin
    • The Word is our offensive weapon (Eph. 6:17).
  • Our confidence rests in Christ’s finished work, not fear of the enemy (Col. 2:15).

We do not command authority, we stand under Christ’s authority, sent by Jesus Himself, faithfully proclaiming His Word and trusting His power to work.
