Because it is written, “YOU SHALL BE HOLY, FOR I AM HOLY.” 1 Peter 1:16
The meaning of the word “Holy” in the Bible is “Set Apart”
Often when people hear the word Holy, they believe you are saying to be “righteous” or “holier than thou” but to truly be a Christian you need to be “Set Apart” . We all probably know a lot of Christians, that if they didn’t tell you they were Christian, you probably would never know. This is not good, and its not being holy
And do not be conformed to this world, but be transformed by the renewing of your mind, so that you may prove what the will of God is, that which is good and acceptable and perfect. Romans 12:2
Don’t follow the ways of this world, renew your mind! This is why God wants us to be “Set Apart”, when you conform to the world , you become corrupted by the world. When you accept immorality that violates the nature of God, you have become corrupted, and are not Holy
Do not think that I came to bring peace on the earth; I did not come to bring peace, but a sword. Matthew 10:34
Jesus brought a sword (The Word of God) to divide the sheep from the goats, to Set Apart the saved from the lost. You should be Set Apart because Christ as Set You Apart by shedding his blood at the cross. You have been Set Apart when you were sealed by the Holy Spirit!
Be Holy because Christ has made you Holy in Jesus Name Amen!
