2 Corinthians 10:12 (Amplified)
One of the problems Paul faced in his life was people who did not respect him or his ministry; this is one of the issues Paul writes about in the second letter to the Corinthians. Some people said that Paul's physical appearance and how he talked was not impressive (2 Corinthians 10:10). Paul's response is that while some people measure and compare themselves with others he was not interested in doing that. As we read in 2 Corinthians 10:12 Paul said people who compare themselves with others and measure themselves by others are not wise.
In Philippians 3 Paul talked about his natural heritage but said all he wanted was to be "found in Christ". Paul knew that the only important thing in life is how we measure up to and compare with what God wants for us. It is easy to start measuring our life and our success by other people but this is a trap the enemy wants us to fall into. God has a plan for our life and how successful we may or may not look compared to other people does not matter as long as we are doing what God wants us to do.
If we try to build our confidence and self worth on how we compare to other people we will get into trouble. God does not want us comparing ourselves to others but He wants us to take a look into His Word and compare ourselves with the standard that we see there. We will get off track with God's plan if we don't follow God's standard but instead look for approval from others and compare ourselves with others. We need to be interested in being approved by God, not people. So, who do you compare to? Let's make it our goal to measure up to the godly standards we see in the Bible and not compare ourselves to other people.
