“All Scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness, that the man of God may be complete, thoroughly equipped for every good work” (2 Timothy 3:16-17).
This is, of course, a passage that is close to the heart of every Christian. It shows how God determined to reveal His will to men, through scripture. God’s Mosaic covenant was to be followed by the Jews. It supplied them everything needed to be prepared for the coming of Jesus (cf. Galatians 3:24-25).
In these last days God has spoken to us “by His Son” (Hebrews 1:2). The words of Jesus, spoken by Him while He was on earth, and given to the disciples (John 16:13) by the Holy Spirit when He departed, constitutes the “faith once for all delivered to the saints” (Jude 3); the “perfect law of liberty” (James 1:25); and “that which is perfect” (1 Corinthians 13:10).
This is clearly affirmed in Hebrews 2:1-4, and makes the words of Peter true when he stated, “no prophecy of Scripture is of any private interpretation, for prophecy never came by the will of man, but holy men of God spoke as they were moved by the Holy Spirit” (2 Peter 1:20-21).
God’s word is how we know His will. We are so thankful for his omniscience and mercy.
