Rejoice always.

Pray without ceasing.

In all circumstances give thanks, for this is the will of God for you in Christ Jesus.

1 Thessalonians 5:16-18

Have no anxiety at all, but in everything, by prayer and petition, with thanksgiving, make your requests known to God.
Then the peace of God that surpasses all understanding will guard your hearts and minds in Christ Jesus.

Philippians 4:6-7
