knowledge about God lesson 4:

Thanks for Their Gifts

10 I rejoiced greatly in the Lord that at last you renewed your concern for me. Indeed, you were concerned, but you had no opportunity to show it.11 I am not saying this because I am in need, for I have learned to be content whatever the circumstances. 12 I know what it is to be in need, and I know what it is to have plenty. I have learned the secret of being content in any and every situation, whether well fed or hungry, whether living in plenty or in want. 13 I can do all this through him who gives me strength.

Basically this verse means 2 things. To be content and to rejoice in the Lord

Psalm 150

1 Praise the Lord.[a]

Praise God in his sanctuary;
    praise him in his mighty heavens.
2 Praise him for his acts of power;
    praise him for his surpassing greatness.
3 Praise him with the sounding of the trumpet,
    praise him with the harp and lyre,
4 praise him with timbrel and dancing,
    praise him with the strings and pipe,
5 praise him with the clash of cymbals,
    praise him with resounding cymbals.

6 Let everything that has breath praise the Lord.

Praise the Lord.

This means to rejoice the lord any way you can.
