As we walk in Holiness, Holiness will be evident by our conversation and actions!
Peter wrote by The Holy Spirit in 1st Peter chapter 1:
13 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.”
17 And if you call on the Father, Who without partiality judges according to each one’s work, conduct yourselves throughout the time of your stay here in fear;
18 knowing that you were not redeemed with corruptible things, like silver or gold, from your aimless conduct received by tradition from your fathers,
19 but with the precious Blood of Christ, as of a lamb without blemish and without spot.
20 He indeed was foreordained before the foundation of the world, but was manifest in these last times for you
21 Who through Him believe in God, Who raised Him from the dead and gave Him glory, so that your faith and hope are in God.
22 Since you have purified your souls in obeying the Truth through the Spirit in sincere Love of the brethren, Love one another fervently with a pure heart,
23 having been born again, not of corruptible seed but incorruptible, through the Word of God which lives and abides forever
And in 2nd Peter chapter 3:
10 But the Day of the Lord will come as a thief in the night, in which the heavens will pass away with a great noise, and the elements will melt with fervent heat; both the earth and the works that are in it will be burned up.
11 Therefore, since all these things will be dissolved, what manner of persons ought you to be in Holy conduct and Godliness,
12 looking for and hastening the coming of the day of God, because of which the heavens will be dissolved, being on fire, and the elements will melt with fervent heat?
13 Nevertheless we, according to His promise, look for new heavens and a new earth in which righteousness dwells.
14 Therefore, beloved, looking forward to these things, be diligent to be found by Him in peace, without spot and blameless;
As we mature in Holiness, we will move away from any action of words that were formerly acceptable. Our interests will change and what we used to think of as priorities will no longer be of any importance. We will become more attentive to those in need and less concerned about ourselves.
What used to stroke our ego will no longer be of importance. When we do something that promotes the ego, The Holy Spirit will gladly point it out in some form of correction. As we mature, there will be less correction required. That is a sign of the maturing process.
Holiness is the one grand end and purpose for which Christ came into the world.
Paul referred to this Truth as he wrote by The Holy Spirit in Ephesians 5:
22 Wives, submit to your own husbands, as to the Lord.
23 For the husband is head of the wife, as also Christ is Head of the church; and He is the Savior of the body.
24 Therefore, just as the church is subject to Christ, so let the wives be to their own husbands in everything.
25 Husbands, Love your wives, just as Christ also Loved the church and gave Himself for her,
26 that He might sanctify 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.
The glorious church will be known by the members’ conversations and actions for they will walk in Holiness, without fault or flaw!
