Holiness is an attribute of God that encompasses all of his other attributes. It is His "God-ness". When we speak of God's holiness we are speaking of His purity, power, perfection, all-sufficiency, eternality, immutability, transcendency , omnipresence, omnipotence, omniscience, righteousness, wisdom, goodness, mercy, sovereignty, faithfulness, love. It is God's holiness that makes Him separate, sacred and above all other things. Nothing can be compared to Him.
