Isaiah 61:3 To appoint unto them that mourn in Zion, to give unto them beauty for ashes, the oil of joy for mourning, the garment of praise for the spirit of heaviness; that they might be called trees of righteousness, the planting of the LORD, that he might be glorified.
Act 2:47 Praising God, and having favour with all the people. And the Lord added to the church daily such as should be saved.
I myself am working on "being anxious for nothing" and making sure to seek to emphasize this in my personal walk with the Lord.
Phl 4:6 Be careful for nothing; but in every thing by prayer and supplication with thanksgiving let your requests be made known unto God.
For me, a strong reminder in the Bible is when Paul and Silas even praised God from a prison cell! Reading this, I realized they weren't just throw into a concrete room on some straw, they had even their feet locked up in stocks!Act 16:23 And when they had laid many stripes upon them, they cast [them] into prison, charging the jailor to keep them safely:
Act 16:24 Who, having received such a charge, thrust them into the inner prison, and made their feet fast in the stocks.
Act 16:25 ¶ And at midnight Paul and Silas prayed, and sang praises unto God: and the prisoners heard them.
Act 16:26 And suddenly there was a great earthquake, so that the foundations of the prison were shaken: and immediately all the doors were opened, and every one's bands were loosed.
