Inspiration is the act where God is the responsible manager and arranger of the Bible through human authorship, so that they recorded without error His message in words of original writings. We see this in 2 Timothy 3:16 “All Scripture is God-breathed and is useful for teaching, rebuking, correcting and training in righteousness, so that the man of God may be thoroughly equipped for every good work.” God spoke the Bible. He was the source by which the original manuscripts, the writings themselves, were inspired. Today when we get inspired to do something, it is an emotional inspiration; something or someone moves us in an emotional way to do something. However, this was not the case with the Biblical writers. The writers were not inspired by God to write the Bible, but rather the writings were inspired.
Inerrancy is derived from the doctrine of Inspiration in that the Bible says scripture is from God; and since God is perfect and cannot lie; the Scriptures are therefore inerrant. Scripture is inerrant in everything that it teaches, whether it is faith, morality, history, science or geography; it is completely true. This is not to say that every copy is without errors, like typos or misspellings, but that every teaching, instruction, action and saying happened, is true, is from God and is without error. Inerrancy also refers to truth. In addition to the character of God who is trustworthy, His word is true. Inerrancy can be supported in John 17:17, where Jesus says, “Sanctify them by the truth; your word is truth.” So, the Bible as the Word of God, which is inspired by God, is true. Feinberg supports this by saying, “Inerrancy is related to Scripture’s intention.” He goes on to say, “Scripture accurately records many things that are false, for example the falsehoods of Satan and human beings.” This is illustrated in the garden when Satan said to Eve in Genesis 3:4, “You will not surely die.” Just because a false statement was made does not make the Bible errant or untrue.
