We very well may have tribulation in this world, but Christ's grace is sufficient for us.
John 15
18 If the world hate you, ye know that it hated me before it hated you.
19 If ye were of the world, the world would love his own: but because ye are not of the world, but I have chosen you out of the world, therefore the world hateth you.
20 Remember the word that I said unto you, The servant is not greater than his lord. If they have persecuted me, they will also persecute you; if they have kept my saying, they will keep yours also.
