I was made very happy in the Lord that now you have revived your interest in my welfare after so long a time; you were indeed thinking of me, but you had no opportunity to show it.
Not that I am implying that I was in any personal want, for I have learned how to be content (satisfied to the point where I am not disturbed or disquieted) in whatever state I am.
I know how to be abased and live humbly in straitened circumstances, and I know also how to enjoy plenty and live in abundance. I have learned in any and all circumstances the secret of facing every situation, whether well-fed or going hungry, having a sufficiency and enough to spare or going without and being in want.
I have strength for all things in Christ Who empowers me [I am ready for anything and equal to anything through Him Who infuses inner strength into me; I am self-sufficient in Christ's sufficiency].
