One verse we read a lot in cute little cards and other quotes is tobe thankful in all things. The key here is 'in' all things. Be thankful for God will bring you through good times and bad to form the person He will use both to help others and serve Him.
Give thanks in all circumstances; for this is God's will for you in Christ Jesus. 1 Thessalonians 5:18
If you read the full chapter it tells us to encourage those who work hard and those who lead us. Then it goes on to point out good things about how He is with us in dark times and good, or light times. It tells us how blessed we are to have Jesus in our lives. We could just read the one verse but seriously go read the full chapter of 1 Thessalonians 5 for yourself! 1 Thessalonians 5:12-13 NIV
Now we ask you, brothers and sisters, to acknowledge those who work hard among you, who care for you in the Lord and who admonish you. Hold them in the highest regard in love because of their work. Live in peace with each other. 1 Thessalonians 5:12-13
It says live in peace with each other. Not at peace. Peace is something of a verb, it is action. Unless it is straight from God peace takes choices and walk through.
You can receive peace too. Accepting peace over fears and trials, worry and troubles, weighting you down .
Its something we decide to do.
Go read the rest of the chapter...
In His Word.
