If we are devoted to the cause of humanity, we shall soon be crushed and broken-hearted, for we shall often meet with more ingratitude from men than we would from a dog; but if our motive is love to God, no ingratitude can hinder us from serving our fellow men. … When we realize that Jesus Christ has served us to the end of our meanness, our selfishness, and sin, nothing that we meet with from others can exhaust our determination to serve men for His sake.
– Oswald Chambers –
