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. If He varied as we do, if He willed one thing today and another tomorrow, if He were controlled by caprice, who could confide in Him? But, all praise to His glorious name, He is ever the same. 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 everything around us. The permanence of God's character guarantees the fulfillment of His promise: "For the mountains shall depart, and the hills be removed: but My kindness shall not depart from thee, neither shall the covenant of My peace be removed, saith the Lord that hath mercy on thee" (Isaiah 54:10).
