"For this is the will of God, your sanctification..." 1 Thessalonians 4:3

Today let us see what Scripture has to say to us concerning sanctification.
The Greek word is HAGIASMOS and "Vine's Expository Dictionary" translates
it sanctification. It is also translated holiness. (I have seen it simply
defined as 'growing in holiness'.)

Scripture tells us it is produced -- By God:
"Now may the God of peace Himself sanctify you entirely; and may your spirit
and soul and body be preserved complete, without blame at the coming of our
Lord Jesus Christ." 1 Thessalonians 5:23

By Christ:
"For both He who sanctifies and those who are being sanctified are all from
one Father, for which reason He is not ashamed to call them brethren."
Hebrews 2:11

By The Holy Spirit:
[To the] "Elect according to the foreknowledge of God the Father, in
sanctification of the Spirit..." 1 Peter 1:2

By truth:
Jesus' prayer to the Father John 17:17,
"Sanctify them by Your truth. Your word is truth."

Concerning the 'word is truth' John tells us:
"In the beginning was the Word, and the Word was with God, and the Word
was God. He (a person not a thing) was in the beginning with God." John
1:1-2
"And the Word became flesh and dwelt among us..." Vs. 14
And John 14:6 says.
"Jesus said to him (Thomas), 'I am the way, the truth, and the life. No one
comes to the Father except through Me."  Jesus IS truth!

Sanctification is the relationship with God that we have entered into by
faith in Christ:
Here Paul is telling King Agrippa how he was apprehended by the Lord Jesus
Christ on the road to Damascus. (Read the account Acts 26:1-19)
Paul asks "...'Who are You, Lord?' And He said, 'I am Jesus, whom you are
persecuting. But rise and stand on your feet; for I have appeared to you for
this purpose to make you a minister and a witness both of the things which
you have seen and of the things which I will yet reveal to you...to open their
(the Jews and the Gentiles) eyes and to turn them from darkness to light,
and from the power of Satan to God, that they may receive forgiveness of
sins and an inheritance among those who are sanctified by faith in Me.'"
Acts 2615-18

1 Corinthians 6:9 tells us,
"Do you not know the unrighteous will not inherit the kingdom of God?"
Then Vs. 11 has that wonderful "but" of God!
"...But you were washed, but you were sanctified, but you were justified in
the name of the Lord Jesus and by the Spirit of God."

"But by His doing you are in Christ Jesus, who became for us wisdom from
God, and righteousness and sanctification and redemption."
1 Corinthians 1:30

So our lives must be befitting of those who are separated!
"For God did not call us to uncleanness, but in holiness."
1 Thessalonians 4:7

"And having been freed from sin, you became slaves of righteousness...so
now present your members as slaves of righteousness, resulting in
sanctification." Romans 6:18-19

"Pursue peace with all men, and holiness, without which no on will see the
Lord." Hebrews 12:14

Concerning the Christian's walk. Paul speaks of its characteristics in
several of his letter--
In new life: "Therefore we were buried with Him through baptism into death,
that just as Christ was raised from the dead by the glory of the Father,
even so we also should walk in newness of life." Romans 6:4

In faith: "For we walk by faith, not by sight." 2 Corinthians 5:7

Spiritually: "I say walk by the Spirit, and you shall not fulfill the lust
of the flesh." Galatians 5:16

In consistency: "I therefore, the prisoner of the Lord, beseech you to have
a walk worthy of the calling with which you were called." Ephesians 4:1
(Read Vs. 1-6)

In love: "And walk in love, as Christ also has loved us and given Himself
for us, an offering and a sacrifice to God for a sweet smelling aroma."
Ephesians 5:2

With caution: "See then that you walk circumspectly (carefully), not as
fools but as wise." Ephesians 5:15

Thank you Lord that we are Yours, that we are works in progress!
"For we are His workmanship, created in Christ Jesus for good works, which
God prepared beforehand that we should walk in them." Ephesians 2:10
Amen
