The Bible <<<is inspired by God and useful for teaching, for conviction, for correction, for education in righteousness, so that the man of God may be fully prepared, fully equipped for every good work>> (2 Tim 3:16-17).
Both the Old and New Testaments are inspired by God. It is the Word of God, the Holy Scriptures (Exodus 32:16, Ps 1-2, 2 Peter 3:16, Jud 1:20, 1 Thess 2:13).
Jesus Christ is the center of Scripture (Lk 24:27, Jn 5:39), both the Old Testament (Jn 7:38, 42) and the New Testament (1 Cor 2:2). The Bible is the Word of Christ (Col 3:16). He himself is the Word (John 1:1-18, Rev 19:13).
The Bible cannot be overruled (John 10:35) or passed away (Matthew 5:18, 24:35). The Word of God remains forever (Is 40:8).
Everything that was written in the OT <<<before was written beforehand for our instruction, so that we might find hope through the perseverance and comfort of the Scriptures>> (Rom 15:4).
Faith comes from proclaiming the Word of God. In God's word we find rebirth (Rom 10:17, 1 Peter 1:23).
The Word of God about <<the Word of the Cross is foolishness to those who are lost; but to us who are saved, it is a God-power>> (1 Corinthians 1:18).
The Word of God is the sword of the flesh (Eph 6:17).
The Word of God <<is living and effective and sharper than any two-edged sword, and it pierces through until it separates both soul and spirit, both marrow and bone, and it is the judge of the thoughts and attitudes of the heart>> (Heb 4:12).
Christians should "let the word of Christ dwell abundantly in you" (Col 3:16).
No one should take anything away from the Word of God or add anything to it (Ge 13:1, Rev 22:18-19).
