Everyone ought to examine themselves.
Long ago, before the invention of mirrors or polished surfaces, people rarely saw themselves. Puddles of water, streams, and rivers were one of the few ways they could see their own reflection. But mirrors changed that. And the invention of cameras took fascination with our looks to a whole new level. We now have lasting images of ourselves from any given time throughout our entire life. This is good for making scrapbooks and keeping family histories, but it can be detrimental to our spiritual well-being. The fun of seeing ourselves on camera can keep us focused on outward appearance and leave us with little interest in examining our inner selves.
Self-examination is crucial for a healthy spiritual life. God wants us to see ourselves so that we can be spared the consequences of sinful choices. This is so important that Scripture says we are not to participate in the Lord’s Supper without first examining ourselves (1 Cor. 11:28). The point of this self-examination is not only to make things right with God but also to make sure we are right with one another. The Lord’s Supper is a remembrance of Christ’s body, and we can’t celebrate it properly if we’re not living in harmony with other believers.
Seeing and confessing our sin promotes unity with others and a healthy relationship with God.
