John 14:27
Peace I leave with you; my peace I give to you. Not as the world gives do I give to you. Let not your hearts be troubled, neither let them be afraid.
Revelation 21:2-5 And I saw the holy city, new Jerusalem, coming down out of heaven from God, prepared as a bride adorned for her husband. 3 And I heard a loud voice from the throne saying, “Behold, the dwelling place of God is with man. He will dwell with them, and they will be his people, and God himself will be with them as their God. 4 He will wipe away every tear from their eyes, and death shall be no more, neither shall there be mourning, nor crying, nor pain anymore, for the former things have passed away.” 5 And he who was seated on the throne said, “Behold, I am making all things new.” Also he said, “Write this down, for these words are trustworthy and true.”
Romans 14:17
For the kingdom of God is not a matter of eating and drinking but of righteousness and peace and joy in the Holy Spirit.
Matthew 6:27
And which of you by being anxious can add a single hour to his span of life?
Isaiah 26:3 You keep him in perfect peace whose mind is stayed on you, because he trusts in you.
Psalm 23:1-4 The Lord is my shepherd; I shall not want. 2 He makes me lie down in green pastures. He leads me beside still waters. 3 He restores my soul.
He leads me in paths of righteousness for his name's sake. 4 Even though I walk through the valley of the shadow of death, I will fear no evil, for you are with me; your rod and your staff, they comfort me.
