who will reward each one according to his works:

For by the grace given to me I say to everyone who is among you not to think more highly of yourself than what one ought to think, but to think {sensibly}, as God has apportioned a measure of faith to each one.

One person prefers [one] day over [another] day, and another person regards every day [alike]. Each one must be fully convinced in his own mind.

So each one of us will give an account concerning himself.

Let each one of us please his neighbor for his good, for the purpose of edification.
