Probably the most damaging, stress and contention causing behavior we can engage in is comparing ourselves to other people…
2 Corinthians 10:12 (KJV)
For we dare not make ourselves of the number, or compare ourselves with some that commend themselves: but they measuring themselves by themselves, and comparing themselves among themselves, are not wise.
2 Corinthians 10:12 (AMP)
Not that we [have the audacity to] venture to class or [even to] compare ourselves with some who exalt and furnish testimonials for themselves! However, when they measure themselves with themselves and compare themselves with one another, they are without understanding and behave unwisely.
Instead we need to examine ourselves and the only comparison we should make is ourselves to Jesus…
2 Corinthians 13:5 (AMP)
Examine and test and evaluate your own selves to see whether you are holding to your faith and showing the proper fruits of it. Test and prove yourselves. Do you not yourselves realize and know [thoroughly by an ever-increasing experience] that Jesus Christ is in you–unless you are [counterfeits] disapproved on trial and rejected?
