I have tried to copy and paste all this proof scripture in order so that you can quickly glance down as you read to see what the actual scripture posted has to say.
Norman Geisler on The Doctrine of Verbal, Plenary Inspiration
"The human writer is seen as one who has received a revelation [revelation means the giving of truth from God, inspiration refers to the recording of this truth] and actively participates in its writing, while God gives the revelation and oversees the writing. Hence, the message is wholly from God, but the humanity of the writer is included to enhance the message. Both the divine and human concur in the same words (1 Cor. 2:13)." [6]
It cannot be overemphasized that inspiration was not a mechanical dictation where the human element of writing was obliterated. God allowed a certain amount of their individual styles to be expressed. Nonetheless, the Holy Spirit of God guided and controlled each writer so that what they wrote was not distorted in any sense, but was what God wanted written. In other words, because God is omnipotent (Rev. 19:6), and the Biblical authors were "born along by the Holy Spirit" (2 Peter 1:21), people did not (in fact, could not) corrupt God's truth in the process of recording it. It is very important to understand these concepts.
The process of inspiration extended to every word of every book of the entire Bible (2 Tim. 3:16 -- "all Scripture"), refuting the idea of myth and error. Jesus taught this, claiming that inspiration extended to the very words (Matt. 5:18), and Paul also believed in the accuracy of the very words (see Gal. 3:16 where he bases his entire argument on the tense of a single word in the Old Testament. He could not have done this if he did not consider the very words accurate). This is called the doctrine of verbal, plenary inspiration, which means that the very words (verbal) were all (plenary) God-breathed. The result must be inerrant and infallible because God is behind the writings, and He is perfect. If it were not inerrant, we would be left with God inspired error (a contradiction in terms!). Jesus said that God's word is truth (John 17:17). Truth is an accurate, undistorted view of reality that is consistent with itself and does not allow for the presence of myths (1 Tim. 1:3, 4; 2 Tim. 4:4), errors, mistakes, or contradictions: "Every word of God is flawless..." (Prov. 30:5). "I, the Lord, speak the truth..." (Isaiah 45:9). That which isn't real, isn't true.
The importance of inspiration
According to 2 Timothy 3:17 there is a reason that all Scripture is God-breathed and therefore without error. In the context of 2 Timothy 3, Paul is talking about the peril of apostasy (false teaching) and the need for protection from it. In order to stand firm in Christ and the truth, we must have a solid foundation, since many will oppose the truth (v. 8), "evil men and impostors will proceed from bad to worse, deceiving and being deceived" (v. 13), and "all who desire to live godly in Christ Jesus will be persecuted" (v. 12). If the Bible contains errors, it is not a solid foundation. Therefore, the entire Bible is God-breathed so that we may "teach, correct, reprove, and train in righteousness, so that the man of God may be adequate, equipped for every good work." If all Scripture is not God-breathed and inerrant, the man of God is not adequate, and certainly not equipped, for doing the work of God. The standard for our beliefs must be fully backed by God's authority, or it will fall, and we will go with it."

“Difficult Times Will Come”
3 But realize this, that in the last days difficult times will come. 2 For men will be lovers of self, lovers of money, boastful, arrogant, revilers, disobedient to parents, ungrateful, unholy, 3 unloving, irreconcilable, malicious gossips, without self-control, brutal, haters of good, 4 treacherous, reckless, conceited, lovers of pleasure rather than lovers of God, 5 holding to a form of godliness, although they have denied its power; Avoid such men as these. 6 For among them are those who enter into households and captivate weak women weighed down with sins, led on by various impulses, 7 always learning and never able to come to the knowledge of the truth. 8 Just as Jannes and Jambres opposed Moses, so these men also oppose the truth, men of depraved mind, rejected in regard to the faith. 9 But they will not make further progress; for their folly will be obvious to all, just as Jannes’s and Jambres’s folly was also.
10 Now you followed my teaching, conduct, purpose, faith, patience, love, perseverance, 11 persecutions, and sufferings, such as happened to me at Antioch, at Iconium and at Lystra; what persecutions I endured, and out of them all the Lord rescued me! 12 Indeed, all who desire to live godly in Christ Jesus will be persecuted. 13 But evil men and impostors will proceed from bad to worse, deceiving and being deceived. 14 You, however, continue in the things you have learned and become convinced of, knowing from whom you have learned them, 15 and that from childhood you have known the sacred writings which are able to give you the wisdom that leads to salvation through faith which is in Christ Jesus. 16 All Scripture is inspired by God and profitable for teaching, for reproof, for correction, for training in righteousness; 17 so that the man of God may be adequate, equipped for every good work.
