Charles H. Spurgeon on Psalms 17:5

In fierce assaults and strong temptations, when Satan layeth siege to the soul, shooting his fiery darts, and using stratagems of policy, joining his endeavours with our corruptions, as wind with tide, then we have cause to pray as David, "Hold up my goings in thy paths, that my footsteps slip not." The apostle also found he had need of help from heaven when he was assaulted, and therefore he prayed "thrice," that the thing that he feared might depart from him. 2 Corinthians 12. Christ hath taught us to pray daily, "Lead us not into temptation," for it is dangerous; and then temptations are most dangerous, when, 1. Most suitable —when Satan joins with our disposition or constitution; 2. Continual; 3. When opportunity and power is greatest. —Joseph Symonds.
