The Hebrew word ‘holy’ (qadosh) probably originally meant ‘separate’ or ‘set apart.’ The word holy means “sacred, set apart from the profane (unholy) and for God.” Baker’s Encyclopedia of the Bible says, “The original Old Testament word for holiness means ‘to cut or to separate.’ Fundamentally, holiness is a cutting off or separation from what is unclean, and consecration to what is pure.” Holiness in the highest sense belongs to God (Isaiah 6:3; Revelation 15:4).
The Holy Spirit Helps Us Gain Holiness!
When I make these mistakes and others, which I do daily, I acknowledge them and thank God for my salvation in Jesus. “If we confess our sins. He is faithful and just to forgive us our sins and cleanse us from all unrighteousness” (I John 1:9).
Here is God’s will, the Spirit’s greatest desire for each one of us. “Do not be conformed to this world, but be transformed by the renewing of your mind (which is the Holy Spirit’s work in us), that you may prove what the will of God is, that which is good and acceptable and perfect” (Romans 12:2).
Peter Explains Holiness!
When Peter speaks in 1 Peter 1:16, he is talking specifically to believers. As believers, we need to be “set apart” from the world unto the Lord. We need to be living by God’s standards, not the world’s. God isn’t calling us to be perfect but to be distinct from the world. 1 Peter 2:9 describes believers as “a holy nation.” It is a fact! We are separated from the world; we need to live out that reality in our day-to-day lives, which Peter tells us how to do in 1 Peter 1:13-16.
