Walkington was Arthur W. Pink's middle name . On this thread I will cite Pink's words from a number of his books -- not only one this time . This opening post will be from : The Immutability Of God chapter in his book : The Attributes Of God . Herein is solid comfort . Human nature cannot be relied upon; but God can ! However unstable I may be , however fickle my friends may prove , God changes not ... His purpose is fixed . His will is stable , His word is sure . Here then is a rock on which we may fix our feet , while the mighty torrent is sweeping away everything around us .
