1 Thessalonians 5:14-18 

  14 Now we exhort you, brethren, warn those who are unruly, comfort the fainthearted, uphold the weak, be patient with all. 15 See that no one renders evil for evil to anyone, but always pursue what is good both for yourselves and for all. 16 Rejoice always, 17 pray without ceasing, 18 in everything give thanks; for this is the will of God in Christ Jesus for you.

Psalms 4:6-8 

6 There are many who say, “Who will show us any good?” Lord, lift up the light of Your countenance upon us.
7 You have put gladness in my heart, More than in the season that their grain and wine increased.
8 I will both lie down in peace, and sleep; For You alone, O Lord, make me dwell in safety.

1 Thessalonians 5:23-24 

23 Now may the God of peace Himself sanctify you completely; and may your whole spirit, soul, and body be preserved blameless at the coming of our Lord Jesus Christ. 24 He who calls you is faithful, who also will do it.
