Charles H. Spurgeon on Psalms 40:17

But I am poor and needy. The man of sorrows closes with another appeal, based upon his affliction and poverty. Yet the Lord thinketh upon me. Sweet was this solace to the holy heart of the great sufferer. The Lord's thoughts of us are a cheering subject of meditation, for they are ever kind and never cease. His disciples forsook him, and his friends forgat him, but Jesus knew that Jehovah never turned away his heart from him, and this upheld him in the hour of need. Thou art my help and my deliverer. His unmoved confidence stayed itself alone on God. O that all believers would imitate more fully their great Apostle and High Priest in his firm reliance upon God, even when afflictions abounded and the light was veiled. Make no tarrying, O my God. The peril was imminent, the need urgent, the suppliant could not endure delay, nor was he made to wait, for the angel came to strengthen, and the brave heart of Jesus rose up to meet the foe. Lord Jesus, grant that in all our adversities we may possess like precious faith, and be found like thee, more than conquerors.
