We know very well that in taking selfies, we tend to use a very useful thing called a filter to filter out our blemishes. Well in the Word of God, there is no filter, and the blemishes we see is sin. We cannot cover it up with a filter, we have to let the Word of God reveal what is sin. In order to know what sin is, we have to be in the Word of God, and we must also surround ourselves with fellow believers who can call us out when we are in sin.
