2 Corinthians 10:2 For we dare not class ourselves or compare ourselves with thosewho commend themselves. But they, measuring themselves by themselves, and comparing themselves among themselves, are not wise.
There is a subtle danger in the Christian life that needs to be guarded against, that is comparing yourself to others. The apostle Paul knew the tendency in human nature to get our eyes off of Jesus and start looking at other people. He said that this was "unwise."
Why is comparing yourself to others in the Christian life, or Christian ministry a danger? There are a few reasons.
When you begin to compare yourself to others it won't be long before you find someone who is not as far along as you are in your walk with the Lord. Perhaps they are still stumbling in sins that you have conquered. As you begin to compare yourself you become inflated with pride. Pride will always quench the work of the Holy Spirit in our lives.
Another result of drawing unwise comparisons is that of discouragement. There are those who are much farther along in their walk with the Lord than you are. They are being used by the Lord in ways that you wish you were being used. They appear to have it together, suddenly you become discouraged and the devil comes in with thoughts of quitting all together. He tells you that you will never make it, and that you are a failure in your faith.
In addition to being filled with pride or being condemned and discouraged, when you compare yourself to others you can become envious and covetous of what someone else has. You can become critical and look for their shortcomings in order to expose them, which in turn somehow puffs you up and draws attention to yourself.
It is unwise to compare ourselves to others. Keep your eyes on Jesus. Grow deeper in love with Him. Learn to be content with whatever state that you are in. Rejoice in the work that God is doing in others. Pray for them. Encourage those who are struggling. Be who Jesus has called you to be.
