A change of life in us is not a single event, it is a process. Holiness is the transformation of the relationship we have with God as we are transformed into the image of God. Holiness does not simply mean to stop sinning or doing wrong things. It is about living for God. Perhaps, we have thought that holiness is something unattainable, or a level we can never reach. But holiness is our new nature; it is a style of thinking and living. We are not saints because of what we do but because of what Christ did for us.
Holiness, unlike legalism, allows us to see our condition as sinners. It is not by works. It is by grace!
