1 Peter 2:9 KJV
[9]But ye are a chosen generation, a royal priesthood, an holy nation, a peculiar people; that ye should shew forth the praises of him who hath called you out of darkness into his marvellous light;
Being different and having such a contrast from the world makes people see the goodness of God. They should see a difference between what they are and what happens under His covering. There’s a peace that’s visible to people, a way of life, speaking, an experience with God everyday. His presence will come daily when we spend time in Him. You are not to be like the world in any way, but to be a light to show others the way. Be attentive to be under that covering and become peculiar and different for Jesus.
Today we read: Psalm 86-88, Psalm 91
