The Apostle Paul tells to rejoice in the Lord always! In fact, he said it twice in a row just in case we missed it the first time. Paul knew about the power of praise when we are going through difficult times. No matter what the situation, rejoice in the Lord always – lift up your voice in praise!
Always be full of joy in the Lord. I say it again—rejoice! Let everyone see that you are considerate in all you do. Remember, the Lord is coming soon. Don’t worry about anything; instead, pray about everything. Tell God what you need, and thank him for all he has done. Then you will experience God’s peace, which exceeds anything we can understand. His peace will guard your hearts and minds as you live in Christ Jesus. Philippians 4:4-7
And I want you to know, my dear brothers and sisters, that everything that has happened to me here has helped to spread the Good News. For everyone here, including the whole palace guard, knows that I am in chains because of Christ. And because of my imprisonment, most of the believers here have gained confidence and boldly speak God’s message without fear. Philippians 1:12-14
Do not be anxious about anything, but in everything, by prayer and petition, with thanksgiving, present your requests to God. And the peace of God, which transcends all understanding, will guard your hearts and your minds in Christ Jesus. Philippians 4:6-7 (NIV)
