And because of God's unearned favor shown to me [i.e., in appointing me to be an apostle], I am telling every person among you not to think he is more important than he really is. Instead, he should have a sensible estimate [of his gifts] in harmony with the degree of faith God has given to each person.

One person regards a certain day more important than another; the next person regards every day alike. Each person should be fully convinced in his own mind [i.e., concerning their relative importance].
