1. The Father’s disciplines His children partnering with the Spirit of God to produce Jesus' holiness in us.
“And you have forgotten the exhortation which speaks to you as to sons: ‘My son, do not despise the chastening of the Lord, nor be discouraged when you are rebuked by Him; for whom the Lord loves He chastens, and scourges every son whom He receives... For they indeed for a few days chastened us as seemed best to them, but He for our profit, that we may be partakers of His holiness. Now no chastening seems to be joyful for the present, but painful; nevertheless, afterward it yields the peaceable fruit of righteousness to those who have been trained by it.”
2. All who claim to be Christians are expected to live a holy life.
“Nevertheless the solid foundation of God stands, having this seal: “The Lord knows those who are His,” and, "Let everyone who names the name of Christ depart from iniquity."” (2 Timothy 2:19)
3. We are to live holy because God says He is holy.
“as obedient children, not conforming yourselves to the former lusts, as in your ignorance; 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.”” (I Peter 1:14-16)
