Banish discouragement from your heart as best you can, and if trouble comes, never let it depress or hinder you for long. At the least, bear it bravely if you cannot bear it cheerfully. Even if you are reluctant to bear it, and feel indignant, yet control yourself, and let no rash words escape you that may harm Christ's little ones. The violence of your feelings will soon subside, and grace return to heal your inner pain. I live, (Isa 49:18) says the Lord, "ready to help and comfort you more than ever, if you will trust Me and call on Me with devotion.
