Roots of the Faith – The Sufficiency and Necessity of Scripture

My sermon notes for Wednesday night, Nov 9th. 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. Our study over the next few months will be “The Roots of the Faith.” This study will focus on key biblical truths that will transform our thinking and allow us to faithfully live out the Christian life. The church provides a live stream of the service each Wednesday at 6:30 on Facebook. We also provide the services through YouTube. You can find Sermon Notes, Family Devotional Guides, Prayer List, and other resources at our Church Website.

The Sufficiency and Necessity of Scripture


  • Since Scripture is inspired and truthful, then it must also be sufficient and necessary.
  • Sola Scriptura – Scripture alone

Sufficiency of Scripture

The sufficiency of Scripture means that Scripture contained all the words of God he intended His people to have at each stage of redemptive history, and that it now contains everything we need God to tell us for salvation, for trusting Him perfectly, and for obeying Him perfectly. (Wayne Grudem)

Necessity of Scripture

Necessity is an attribute of Scripture whereby it is essential for knowing the way of salvation, for progressing in holiness, and for discerning in God’s will. (Gregg Allision)


  • 2 Tim 3:16-17
  • Psalm 119 (some many verses!)
  • Deuteronomy 4:1-2; 6:6-7; 12:32
  • Proverbs 30:5-6
  • Romans 10:13-17
  • Matthew 4:4

Allow Scripture to guide your life

  • Scripture enables us to know Him (Salvation)
  • Scripture enables us to live for Him (Sanctification)
    • We need nothing else
  • We need to answer the questions of the day through the “lens of Scripture”
  • How to think about an issue
  • What to do in a situation
  • Psalm 32:8 – Instruct, Teach… the way you should go.
  • It will not answer every question we may ask, but it will answer the questions that pertain to my salvation and holiness!  How to know and live for the Lord.
  • Deut 29:29 – Secret things belong to God

Search Scripture for answers

  • We need to answer the questions of the day through the “lens of Scripture”
  • Not feeling
  • Not impressions
  • Not advice from the experts
  • Search the Word

Do not add to Scripture

  • Rev. 22:18
  • Book of Mormon
  • Traditions of the Church
    • Pope
  • Modern day prophet/new word
  • Adding legalistic requirements
