If you notice, the root word for "sanctification" is always G-38. Looking up G-38, you will see that underneath the definition is a list of all of the words used from that specific Greek word.
Besides "sanctification," G-38 is also translated as "holiness." Now, look up the word "holiness" and find those with the root word G-38. Here are all of the words that I found with the root G-38 (both "holiness" and "sanctification"):
"I speak after the manner of men because of the infirmity of your flesh: for as ye have yielded your members servants to uncleanness and to iniquity unto iniquity; even so now yield your members servants to righteousness unto holiness." (Romans 6:19)
"But now being made free from sin, and become servants to God, ye have your fruit unto holiness, and the end everlasting life." (Romans 6:22)
"But of him are ye in Christ Jesus, who of God is made unto us wisdom, and righteousness, and sanctification, and redemption:" (1 Corinthians 1:30)
"For this is the will of God, even your sanctification, that ye should abstain from fornication:" (1 Thessalonians 4:3)
"That every one of you should know how to possess his vessel in sanctification and honour;" (1 Thessalonians 4:4)
"For God hath not called us unto uncleanness, but unto holiness." (1 Thessalonians 4:7)
"But we are bound to give thanks alway to God for you, brethren beloved of the Lord, because God hath from the beginning chosen you to salvation through sanctification of the Spirit and belief of the truth:" (2 Thessalonians 2:13)
"Notwithstanding she shall be saved in childbearing, if they continue in faith and charity and holiness with sobriety." (1 Timothy 2:15)
"Follow peace with all men, and holiness, without which no man shall see the Lord:" (Hebrews 12:14)
"Elect according to the foreknowledge of God the Father, through sanctification of the Spirit, unto obedience and sprinkling of the blood of Jesus Christ: Grace unto you, and peace, be multiplied." (1 Peter 1:2)
Do We Need Other Books?
Is God's Word really enough for the believer, or do we need other books to help us along? While study books can be extremely helpful, I would caution any Christian in using "other books." Persuasive authors can use Scripture out of context and if we are not careful to use the Bible as our "plumb line," we can very easily be swayed to believe something that is not fully truth. Let us take into consideration the question at hand. Why would one think that the Bible is not enough? We can read many authors, some of which will claim that we only need the Bible, others who will claim that we need extra curriculum. Well, what does the Bible Itself say about this issue?
"For whatsoever things were written aforetime were written for our learning, that we through patience and comfort of the Scriptures might have hope." (Romans 15:4)
"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 perfect, throughly furnished unto all good works." (2 Timothy 3:16-17)
"According as His divine power hath given unto us all things that pertain unto life and godliness, through the knowledge of Him that hath called us to glory and virtue: Whereby are given unto us exceeding great and precious promises: that by these ye might be partakers of the divine nature, having escaped the corruption that is in the world through lust." (2 Peter 1:3-4)
"As ye have therefore received Christ Jesus the Lord, so walk ye in Him: Rooted and built up in Him, and stablished in the faith, as ye have been taught, abounding therein with thanksgiving. Beware lest any man spoil you through philosophy and vain deceit, after the tradition of men, after the rudiments of the world, and not after Christ." (Colossians 2:6-8) (emphasis added)
If still in doubt after reading these passages, I would recommend you to read Psalm 119 and see what God thinks about His Word. Just as God opened the understanding of His disciples to know what His Word says ("Then opened He their understanding, that they might understand the scriptures," Luke 24:45), God will open our understanding.
As this series concludes, may we apply ourselves to diligently study God's Word in 2014 so that
Jesus will not have to say to us as to the Pharisees, "Did ye never read in the scriptures. . ." (Matthew 21:42) or as to the Sadducees, "Ye do err, not knowing the scriptures, nor the power of God." (Matthew 22:29)
