God always attacks you in the weak point. You do not try to kill someone by hitting them where they are strongest. You have to aim at your vital organs: the bosom of life. When God aims to kill your old nature, He touches the most tender point ... the point that overflows lifetime! This is why it offers the kind of trials He gives you.
Let yourself be humiliated. If you are silent and peaceful when humiliating things happen to you, you will grow in grace. I realize that you You will be tempted to defend yourself for thousands of different reasons. But it is much better to be humbly silent. The humility that still you can talk, you have to look at it more closely. You lick too much wounds when you speak.
Do not get too upset when they say things about you. Let the speak world; it only seeks to do God's will. You will never be able to completely satisfy people, and the painful effort is not worth it.

People come and go ... let them do what they like. Look to God only. He is the one that afflicts or comforts you through people and circumstances. He does it for your own benefit.
