“Sanctify them by Your truth. Your word is truth.”

Sanctify them by Your truth. Your word is truth.
18 As You sent Me into the world, I also have sent them into the world.
19 And for their sakes I sanctify Myself, that they also may be sanctified by the truth.
John 17.17-19

“‘but as He who called you is holy, you also be holy in all your conduct, because it is written, ‘Be holy, for I am holy.'”

Living Before God Our Father
Therefore gird up the loins of your mind, be sober, and rest your hope fully upon the grace that is to be brought to you at the revelation of Jesus Christ; 14 as obedient children, not conforming yourselves to the former lusts, as in your ignorance; 15 but as He who called you is holy, you also be holy in all your conduct, 16 because it is written, “Be holy, for I am holy.”
1 Peter 1.13

“what sort of people ought you to be in lives of holiness and godliness”

But the day of the Lord will come like a thief, and then the heavens will pass away with a roar, and the heavenly bodies will be burned up and dissolved, and the earth and the works that are done on it will be exposed.
11 Since all these things are thus to be dissolved, what sort of people ought you to be in lives of holiness and godliness, 12 waiting for and hastening the coming of the day of God, because of which the heavens will be set on fire and dissolved, and the heavenly bodies will melt as they burn! 13 But according to his promise we are waiting for new heavens and a new earth in which righteousness dwells.
2 Peter 3.10-13

“By that will we have been sanctified (set apart) through the offering of the body of Jesus Christ once for all.”

Previously saying, “Sacrifice and offering, burnt offerings, and offerings for sin You did not desire, nor had pleasure in them” (which are offered according to the law), ⁹ then He said, “Behold, I have come to do Your will, O God.” He takes away the first that He may establish the second. ¹⁰ By that will we have been ^[c]sanctified (set apart) through the offering of the body of Jesus Christ once for all.
Hebrews 10.8-10

“For by one offering He has perfected forever those who are being sanctified (set apart).”

Christ’s Death Perfects the Sanctified
And every priest stands ministering daily and offering repeatedly the same sacrifices, which can never take away sins. 12 But this Man, after He had offered one sacrifice for sins forever, sat down at the right hand of God, 13 from that time waiting till His enemies are made His footstool. 14 For by one offering He has perfected forever those who are being [d] sanctified (set apart).
Hebrews 10.11-14

“no fornicator, unclean person, nor covetous man, who is an idolater, has any inheritance in the kingdom of Christ and God”

Walk in Love
Therefore be imitators of God as dear children. 2 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.
3 But fornication and all uncleanness or covetousness, let it not even be named among you, as is fitting for saints; 4 neither filthiness, nor foolish talking, nor coarse jesting, which are not fitting, but rather giving of thanks. 5 For this you know, that no fornicator, unclean person, nor covetous man, who is an idolater, has any inheritance in the kingdom of Christ and God. 6 Let no one deceive you with empty words, for because of these things the wrath of God comes upon the sons of disobedience. 7 Therefore do not be partakers with them.
Ephesians 5.1-7

“that He might sanctify (set it apart) and cleanse her with the washing of water by the word,

that He might present her to Himself a glorious church, not having spot or wrinkle or any such thing, but that she should be holy and without blemish“

Marriage—Christ and the Church
Husbands, love your wives, just as Christ also loved the church and gave Himself for her, 26 that He might [g] sanctify (set it apart) and cleanse her with the washing of water by the word, 27 that He might present her to Himself a glorious church, not having spot or wrinkle or any such thing, but that she should be holy and without blemish. 28 So husbands ought to love their own wives as their own bodies; he who loves his wife loves himself.
29 For no one ever hated his own flesh, but nourishes and cherishes it, just as the Lord does the church. 30 For we are members of His body, of His flesh and of His bones. 31 “For this reason a man shall leave his father and mother and be joined to his wife, and the two shall become one flesh.” 32 This is a great mystery, but I speak concerning Christ and the church. 33 Nevertheless let each one of you in particular so love his own wife as himself, and let the wife see that she respects her husband.
Ephesians 5.25-33

“Pursue peace with all people, and holiness, without which no one will see the Lord”

Renew Your Spiritual Vitality
Pursue peace with all people, and holiness, without which no one will see the Lord: 15 looking carefully lest anyone fall short of the grace of God; lest any root of bitterness springing up cause trouble, and by this many become defiled; 16 lest there be any fornicator or profane person like Esau, who for one morsel of food sold his birthright. 17 For you know that afterward, when he wanted to inherit the blessing, he was rejected, for he found no place for repentance, though he sought it diligently with tears.
Hebrews 12.14-17

“perfecting holiness in the fear of God”

Therefore, having these promises, beloved, let us cleanse ourselves from all filthiness of the flesh and spirit, perfecting holiness in the fear of God.
2 Corinthians 7.1

“the fear of the Lord”

“Keep your tongue from evil,
And your lips from speaking deceit.
Depart from evil and do good;
Seek peace and pursue it.”

Come, you children, listen to me;
I will teach you the fear of the Lord.
12 Who is the man who desires life,
And loves many days, that he may see good?
13 Keep your tongue from evil,
And your lips from speaking deceit.
14 Depart from evil and do good;
Seek peace and pursue it.
Psalm 34.11-14
