Charles H. Spurgeon on Psalms 78:42

They remembered not his hand, etc. The rallying point of faith in time of trial is the primary manifestation of grace. To an Israelite a remembrance of the deliverance from Egypt is the test of active faith. In like manner, to the tried believer now it is the CROSS that furnishes the outlet of deliverance from the misty darkness with which Satan sometimes is permitted to envelope our conscience, when the Lord had not been kept watchfully before our face. Because Israel forgot that first deliverance, they went on frowardly in the way of evil. Because a Christian sometimes stops short of the Cross in his spiritual conflicts, he fails to defeat the enemy and remains unfruitful and unhappy, until by some special intervention of the great Restorer, he is again brought, in spirit, to that place where God first met him, and welcomed him in Jesus in the fulness of forgiveness and of peace. No intermediate experience, how truthful soever in its character, will meet his case. It is at the cross alone that we regain a thorough right mindedness about ourselves as well as about God. If we would glorify him, we must "hold fast the beginning of our confidence stedfast unto the end, "Heb 3:14. Arthur Pridham.
