John 16:33

I have told you this so that you will have peace by being united to me. The world will make you suffer. But be brave! I have defeated the world!

Do you ask the reason for suffering, believer? Look upward to your heavenly Father, and behold him pure and holy. Do you know that you will one day be like him? Will you easily become conformed to his image? Won't you require much refining in the furnace of affliction to purify you? Will it be an easy thing to get rid of your corruptions, and make you perfect even as your Father which is in heaven is perfect? Next, Christian, turn your eyes downward. Do you know what foes you have in the world? You were once a servant of Satan, and no king will willingly lose his subjects. Do you think that Satan will leave you alone? No, he will be always at you, for he "goes about like a roaring lion, seeking whom he may devour." Christian, expect trouble when you look at the world around you. Where are you? You are in an enemy's country, a stranger and a sojourner. The world is not your friend. If it is, then you are not God's friend, for he who is the friend of the world is the enemy of God. Be assured that you shall find enemies everywhere. When you sleep, remember that you are resting on the battlefield, When you walk, suspect an ambush in every hedge. As mosquitoes are said to bite strangers more than natives, so will the trials of earth be hardest on you. Lastly, look within yourself, into your own heart and observe what is there. Sin and self are still within. Aha! if you had no devil to tempt you, no enemies to fight you, and no world to ensnare you, you would still find in yourself enough evil to be a sore trouble to you, for "the heart is deceitful above all things, and desperately wicked." Expect trouble then, but do not get depressed because of it, for God is with you to help and to strengthen you. He has said, "I will be with you in trouble; I will deliver you and honor you."
