Have I learned? Learned to be content with whatsoever may be my lot?
The answer to this pointed, definitely personal question the word of God in this passage would elicit from our hearts.
Let us not overlook two features of the text. First, it is a personal profession. Second, it speaks of contentment as a lesson that must be learned. As a personal confession it purposes to have a place in our own hearts and upon our own lips, so that we have really not heard the word of God until we, you and I can repeat it after the apostle with personal application: I have learned to be content with whatsoever may be my state.
