The concept of grace is all that defines our relationship with God. If you fail to understand this, you will never understand Christianity. It is all about God’s grace that we overcome the devil and all tribulations and troubles of life.
Jesus identified us as light that cannot be hidden. You cannot be a secret Christian. The light in us represents our life source. It represents the kind of life we should have as Christians. God kept us here so that we can show this dark world what it means to have the light of God.
