How do we know holiness is important for Christians?

Holiness is a central aspect of Christian faith, signified in Obadiah 1:17 where it states, 'there shall be holiness.' This underscores the importance of being set apart unto God, which is essential for any believer desiring to dwell in God’s presence. In Hebrews 12:14, the Scripture exhorts, 'Follow peace with all men, and holiness, without which no man shall see the Lord.' This implies that without holiness, one cannot experience the full fellowship with God. Our holiness is rooted in Christ, for He is the Holy One of Israel. As believers are united with Him, they are declared holy and are to pursue a life reflecting that holiness in their actions and relationships. Holiness therefore signifies both our standing before God and the ongoing work of sanctification in our lives.
