Hello Jeff,
The "twisting" of scripture is one thing, a warning all round.
2 Peter 3:16-18 (New International Version)
16 He writes the same way in all his letters, speaking in them of these matters. His letters contain some things that are hard to understand, which ignorant and unstable people distort, as they do the other Scriptures, to their own destruction.
17 Therefore, dear friends, since you already know this, be on your guard so that you may not be carried away by the error of lawless men and fall from your secure position. 18 But grow in the grace and knowledge of our Lord and Savior Jesus Christ. To him be glory both now and forever! Amen.
Acts 20:28-32 (New International Version)
28 Keep watch over yourselves and all the flock of which the Holy Spirit has made you overseers. Be shepherds of the church of God, which he bought with his own blood. 29 I know that after I leave, savage wolves will come in among you and will not spare the flock. 30 Even from your own number men will arise and distort the truth in order to draw away disciples after them. 31 So be on your guard! Remember that for three years I never stopped warning each of you night and day with tears.
32 "Now I commit you to God and to the word of his grace, which can build you up and give you an inheritance among all those who are sanctified.
2 Corinthians 4:1-4 (New International Version)
1 Therefore, since through God's mercy we have this ministry, we do not lose heart. 2 Rather, we have renounced secret and shameful ways; we do not use deception, nor do we distort the word of God. On the contrary, by setting forth the truth plainly we commend ourselves to every man's conscience in the sight of God. 3 And even if our gospel is veiled, it is veiled to those who are perishing. 4 The god of this age has blinded the minds of unbelievers, so that they cannot see the light of the gospel of the glory of Christ, who is the image of God. Revelation 22:18-21 (New International Version)
18 I warn everyone who hears the words of the prophecy of this book: If anyone adds anything to them, God will add to him the plagues described in this book. 19 And if anyone takes words away from this book of prophecy, God will take away from him his share in the tree of life and in the holy city, which are described in this book.
20 He who testifies to these things says, "Yes, I am coming soon."
Amen. Come, Lord Jesus.
21 The grace of the Lord Jesus be with God's people. Amen.
Notice in each of the these warnings, the grace of Jesus is mentioned directly afterwards i.e. the free gift of salvation. As for how to read the bible, there is only one way (if you want to use it for its true purpose).
John 5:39-40 (New International Version)
39 You diligently study the Scriptures because you think that by them you possess eternal life. These are the Scriptures that testify about me, 40 yet you refuse to come to me to have life.
1 Corinthians 2:14 (New International Version)
14 The man without the Spirit does not accept the things that come from the Spirit of God, for they are foolishness to him, and he cannot understand them, because they are spiritually discerned.
John 14:26 (New International Version)
26 But the Counselor, the Holy Spirit, whom the Father will send in my name, will teach you all things and will remind you of everything I have said to you.
John 15:26 (New International Version)
26 "When the Counselor comes, whom I will send to you from the Father, the Spirit of truth who goes out from the Father, he will testify about me.
Blessings,
Stephen
