Know That You Know

Assurance isn’t a feeling—it’s a foundation. In this session, Dean Miller opens 1 John to expose the enemies of assurance and points us to the finished work of Christ, the faithful witness of the Spirit, and the forever-settled Word. Know that you’re saved, and grow into a life that conquers the flesh, the world, and the wicked one.

Dean Miller opens 1 John to show how believers can live in settled assurance. He walks through the three great enemies—the flesh, the world, and the devil—and how assurance grows when we confess sin, love the Father over the world’s system, and rest in Christ’s finished work, the Spirit’s witness, and the Scripture’s record. The result: confidence to “know and grow” in daily victory. 

Topics Discussed

  • 1 John as a book of assurance: why “if you don’t know it, you won’t grow it.” 
  • Enemy #1: the flesh; keeping short accounts and obeying Christ (1 Jn 1–2). 
  • Enemy #2: the world—lust of the flesh, eyes, and pride of life—and choosing the Father’s love. 
  • Enemy #3: the spirit of antichrist; overcoming by the finished work of Christ, the Spirit’s witness, and the forever-written Word. 
  • Practical pathways to assurance: confession, obedience, affection for the church, and trusting God’s record. 

Key Takeaways

  • Unconfessed sin disrupts fellowship and fuels doubt; confession restores assurance. 
  • You can’t love the world’s system and love the Father at the same time. Choose the Father. 
  • Assurance rests on three anchors: Christ’s finished work, the Spirit’s faithful witness, and the Scripture’s forever record (1 John 5:6–13). 
  • “When you know you’re saved, you can grow in victory.”
