"Do all things without complaining or arguing, so that you may become blameless and pure, children of God without fault in a crooked and depraved generation, in which you shine like stars in the universe."
Philippians 2:14-15

'Without complaining or arguing'
Other translations use such words as:
Murmurings and questionings; grumbling and faultfinding; And The Twentieth Century New Testament translates Vs. 14 as, "In all that you do, avoid discontent and dissension."

We are to be content in all that God has called us to do in each situation He has prepared for us. For verse 13 has just reminded us that, "For it is God who is at work in you, both to will and to work for His good pleasure."
And in Ephesians 2:10 (a verse we know well), "For we are God's workmanship, created in Christ Jesus to do good works, which God prepared in advance for us to do."

Of contentment, the Apostle Paul tells the Philippians in Chapter 4 "...I have learned to be content whatever the circumstances. Vs. 11 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." Vs. 12 How does he know?
"I can do everything through Him who gives me strength." Vs. 13 Then he encourages the Philippians and us with this truth, "And my God will meet all your needs according to His glorious riches in Christ Jesus." Vs 19

And why are we to be content in doing all things?
'So that you may become blameless and pure...without fault in a crooked and depraved generation...' Vs. 15 of our opening verses.

Both Apostles Paul and Peter in their letters encourage their reads in becoming blameless:
"And although you were formally alienated and hostile in mind, engaged in evil deeds, yet He has now reconciled you in His fleshly body through death, in order to present you before Him holy and blameless and beyond reproach."
Colossians 1:21-22

"May He strengthen your hearts so that you will be blameless and holy in the presence of our God and Father when our Lord Jesus comes with all His holy ones." 1 Thessalonians 3:13

"Therefore, beloved, since your are looking for these things (new heavens and a new earth), be diligent to be found by Him in peace, spotless and blameless." 2 Peter 3:14 (The 'these things' are spoken of in the previous
verse.)

As children of God we are to be above reproach in this crooked and depraved generation. Paul states it clearly in Ephesians 5, "Therefore, be imitators of God, as beloved children." Vs. 1 "For you were once darkness, but now you are light in the Lord. Live as children of light (for the fruit of the light consists in all goodness, righteousness and truth)..." Vs. 8-9 And, "Be very careful, then how you live--not as unwise but as wise, making the most of every opportunity, because the days are evil.
Therefore, do not be foolish, but understand what the Lord's will is."
Vs. 15-17

I close with Romans 12:2 (a very familiar admonition to us all), "...Be transformed by the renewing of your mind, that you may prove what the will of God is, that which is good and acceptable and perfect.,"

We trust the Holy Spirit to lead and guide us into all truth as Jesus promised. And we thank Almighty God for His gracious goodness for all things. Amen
