4 Bible Verses about Self Examination

So, a person should examine himself [first] and then he should eat the bread and drink from the cup.

Put yourselves to a test; see if you are [really] in the faith [i.e., see if you are genuine Christians]; examine yourselves! Or, do you not realize that Jesus Christ is in your hearts, unless [of course] you fail the test [i.e., unless you are counterfeit Christians].

But if we [had] examined ourselves [properly], we would not be [i.e., not have been] judged [i.e., with sickness and death. See verse 30].

But let each person test his own accomplishments so that he can determine if he should get credit for them or if his neighbor should.
