The lives of the saints are littered with stressful and painful trials, tribulations and selfless sacrifice. So how is it that Jesus can say "Come to me, all who labor and are heavy laden, and I will give you rest. 29 Take my yoke upon you, and learn from me; for I am gentle and lowly in heart, and you will find rest for your souls. 30 For my yoke is easy, and my burden is light.” - Matthew 11?
Does it have something to do with this? “Peace I leave with you; my peace I give to you; not as the world gives do I give to you.” - John 14
