24 This is the disciple who testifies of these things, and wrote these things; and we know that his testimony is true. 25 And there are also many other things that Jesus did, which if they were written one by one, I suppose that even the world itself could not contain the books that would be written. Amen. (John 21:24–25, NKJV)
Countless books have been written through the ages. The economy and efficiency of the sixty-six books of the Bible are especially impressive compared to books of human origin. These traits of the Bible are faith-building as they teach us to be content with what the Lord has revealed. We do not add to the word of God because the inspired Scriptures are sufficient to thoroughly equip the person of God for every good work (2 Tim. 3:16-17). We affirm the faith was once for all delivered to the saints (Jude 3). The Scriptures do not contain everything Jesus said or did, but they are the complete message God intended us to have (v. 25). The Scriptures give trustworthy testimony and ample evidence that “Jesus is the Christ, the Son of God,” so that by “believing you may have life in His name” (v. 24; Jno. 20:30-31). Not every appearance of Jesus after His resurrection is in the Scriptures, but enough “infallible proofs” are there to certify He lives (Acts 1:3; 1 Cor. 15:4-8). The Scriptures do not memorialize every lesson Jesus taught His apostles about the kingdom of God, but later they would preach the gospel of the kingdom as the “whole counsel of God” (Acts 20:24-27). Respect for God’s word includes being satisfied with what God has revealed and being humble enough to accept it as sufficient for “life and godliness” (2 Pet. 1:3-4).
