- The New Testament claims to be the source of authority for all we do of eternal importance, no matter when or where we live (Col. 3:17; 2 Pet. 1:3,20-21; 2 Tim. 3:16-17).
- The New Testament will not share authority with any other book or “revelation” (Gal. 1:6-9; Jude 3).
- The New Testament reveals how a person becomes a Christian (Acts 2:37-47; Eph. 4:4-6).
- The New Testament teaches us that the Lord adds Christians to His church (Acts 2:47).
- The New Testament shows us how that church is organized and led (Acts 20:28; 1 Tim. 3:1-12; Phil. 1:1; 1 Pet. 5:1-4).
- The New Testament gives us the day the Christians met to worship (Acts 20:7; 1 Cor. 16:1-2).
- The New Testament clarifies for us the various roles and responsibilities God has given to each gender of Christians in the work and worship of His church (1 Tim. 2:8-15).
- The New Testament teaches the Christian how God wants to be worshipped (John 4:24).
- The New Testament outlines the Christian’s purpose and work (Eph. 4:11-16).
- The New Testament is dedicated to showing how one, as a faithful Christian, has eternal life and the hope of heaven (Ti. 1:2; Rev. 2:10; ch. 21-22).
- The New Testament helps one understand how God wants marriage and family to function, to build Christian homes (Mat. 19:1-12; Eph. 5:22-6:4; 1 Pet. 3:1-7).
- The New Testament urges Christian growth and thoroughly teaches how that is accomplished (2 Pet. 3:18; Ti. 2:11-14; John 15:1ff; etc.).
- The New Testament constantly speaks of how the Christian needs to and benefits from developing an intimate relationship with the Godhead (1 Th. 5:17; 2 Tim. 2:15; John 15:14; Mat. 22:36-40).
- The New Testament teaches that Christians prove to others their discipleship to Christ by loving one another (John 13:34-35).
- The New Testament reveals that Christians are tasked with duplicating themselves by teaching the gospel to those outside of Christ (Mat. 28:18-20; Acts 8:4; Col. 1:23).
- The New Testament asserts itself as the unfailing, universal guide regarding anything that will ultimately matter (2 Pet. 1:3; John 14:26; 16:13; etc.).
If what we are after is divine guidance for who a Christian is, what he or she does, and how God wants one to live, where else would we turn but to the New Testament? A God who engineered us for eternity and tells us we have but two eternal dwelling places would be cruel and unloving if He did not give us clear, thorough answers to any matter that is important to Him. How loving and faithful for God to give us such an unambiguous guide.
