First of all the scripture says to examine your selves, it makes no mention of examining others. We often examine other people as soon as we see them or hear them talking. We are very quick to form opinions of others even when we know nothing about the person.
Paul tells us how we are to examine our selves but he never tells us how to judge other people. He begins be telling us to examine whether we are in the faith or not in the faith. If we examine ourselves and find that we are not in the faith we need to make some changes in our way of living.
He tells us that one thing that we must do and that is to prove ourselves. This is something that we probably would not really enjoy because we probably have a few things that might embarrass ourselves. We already know what they are but we don’t want to dig them up again. We need to be more concerned about ourselves than we do of others.
The reason he tells us to know our own selves so that we might remember our own weaknesses as we look to others to try to help them. If we could only look to our selves and see our own problems perhaps we could better help others because we would be looking with understanding. If we could realize that we have the same problems as others have then every thing would change. We look at the problems of others very critically while we ignore our own problems.
What we need to do in looking at ourselves is to find Christ as a big part of our lives. We know that without Christ there will be no salvation unless we change so let us understand our own problems first. Christ is the only way to take care of these problems and make us able to secure our own eternal life and then we can help others.
