So long as we're in this world, we will experience tribulation. But through faith, you can receive and maintain the peace of Christ in your heart.

I will praise You, O Lord, with my whole heart; I will tell of all your marvelous works. I will be glad and rejoice in you; I will sing praise to Your name, O Most High. —Psalm 9:1-2

Your word I have hidden in my heart, that I might not sin against You. —Psalm 119:11
