I am currently reading J.I. Packer's Rediscovering Holiness in my devotions and I am finding so many pearls of wisdom. He argues that one of the main weaknesses of the Evangelical Western Church is its lack of holiness and I completely agree. Here are some nuggets I've gleaned so far:

"Holy in both biblical languages means separated and set apart for God, consecrated and made over to him." (p. 19)

"Genuine holiness is genuine Christ-likeness, and genuine Christ-likeness is genuine humanness-the only genuine humanness there is. Love in the service of God and others, humility and meekness under the divine hand, integrity of behavior expressing integration of character, wisdom with faithfulness, boldness with prayerfulness, sorrow at people's sins, joy at the Father's goodness, and single-mindedness in seeking to please the Father morning, noon, and night, were all qualities seen in Christ, the perfect man. Christians are meant to become human as Jesus was human." (p. 28)

"In reality holiness is the goal of our redemption." (p. 35)

"When we confess ourselves lost sinners and cast ourselves on Christ to save us, we are acknowledging by our action that we contribute nothing to our new relationship with God save our need of it, and this is the exact truth. We get into God's favor, not by paying our way, but by accepting his gift of a blood-bought amnesty. However, in sanctification, which is the work of God within us from which our holiness flows, we are called to cooperate actively with God." (p. 45)

A holy life begins with being awestruck at the greatness of my Maker, gratitude for the mercy of my God, being zealous for the glory of my Savior Jesus Christ, and being natural in the living of my life (being led by the Holy Spirit). (Chapter 3)

"A paradox of Christian holiness that mystifies outsiders is that, despite the privations that Jesus described as self-denial, cross-bearing, cutting off one's hand and foot, gouging out one's eye, leaving wealth and security for poverty and some measure of persecution, holiness is essentially a happy business." (p. 87)

"Holiness is every Christian's calling. It is not an option, but an requirement. God wants his children to live up to his standards and to do him credit in the eyes of the watching world, so he says explicitly to us all: 'Be holy, because I am holy' (1 Pet.1:16)." (p. 90-91)

"Holy people practice good works, not to earn God's present or future favor, but as a way of laying hold of that for which Christ has laid hold of them." (p. 105)
