1 Peter 1:13-16 commands us to prepare ourselves and focus upon Christ rather than this world in becoming more Holy. Peter actually quotes Leviticus 11:45 in his letter. Peter continues to talk about holiness in 2 Peter 3:11-14. He tells us that we should be people waiting for the return of Jesus Christ and that while we wait... “we ought to live holy and godly lives.”
"A Long Obedience in the Same Direction", by Eugene Peterson reads, it is not difficult in our world to get a person interested in the message of the Gospel; it is terrifically difficult to sustain the interest. Millions of people in our culture make decisions for Christ, but there is a dreadful attrition rate. Many claim to have been born again, but the evidence for mature Christian discipleship is slim. In our kind of culture anything, even news about God, can be sold if it is packaged freshly; but when it loses its novelty, it goes on the garbage heap. There is a great market for religious experience in our world; there is little enthusiasm for the patient acquisition of virtue, little inclination to sign up for a long apprenticeship in what earlier Christians called holiness.
As you can see in this psalm if you could use just one word to describe God I believe it would be “Holy!” When we pick up our hymnal and sing praises to God, do we sing “Awesome, awesome, awesome, Lord God Almighty?” No! We sing “Holy, Holy, Holy, Lord God Almighty.”
In Isaiah chapter 6, Isaiah said, “I saw the Lord sitting on a throne, high and lifted up, and the train of His robe filled the temple. Above it stood Seraphim, each had six wings; with two he covered his face, with two he covered his feet, and with two he flew. And one cried out to another and said, Love, Love, Love is the Lord God Almighty! Eternal, Eternal, Eternal is the Lord God Almighty? Faithful, Faithful, Faithful is the Lord God Almighty? Wise, Wise, Wise is the Lord God Almighty?” No! No! No! They cried out, “Holy, Holy, Holy is the Lord of Hosts, the whole earth is full of His glory.”
Folks, God is Holy! Holiness is probably the most significant of all of God’s characteristics. The word “Holy” in the Greek is the word “Hagios”, which means separateness, a separation from sin or any kind of evil or impurity. God is the only One who possesses that characteristic in absolute perfection. Psalm 111:9 says, “Holy and reverent is His name.”
Job 6:10 refers to God as “The Holy One.” I Samuel 2:2 says, “There is none Holy like the Lord for there is none besides Thee.” (Again that’s a part of the Holy, Holy, Holy hymn)
Folks, when we look at the word of God we see the words “Holy Bible.” His word is Holy. Not only is His word Holy, His day is Holy. In the Old Testament when the Tabernacle was assembled, the place behind the veil, where the Ark of the Covenant was located was called “The Holy of Holies” because that’s where God was. He said, “To those who approach Me I will show Myself Holy.” He even tells us to be Holy because He is Holy (Lev. 11:45).
