Newton on Temptation

God has wise and gracious ends in permitting Christians to be tossed with tempest, and not comforted. Ere long these designs will be more fully unfolded to us; and we shall be satisfied that He has done all things well. In the meanwhile, it is our duty, and will be much for our comfort, to believe it upon the authority of His word.

Prayer, which at all times is necessary, is especially so in a time of temptation. But how hard it is to come boldly, that we may obtain help in our time of need! But however hard, it must be attempted
(Newton goes on to point out that if Satan cannot stop us from praying, he will attempt to make us legalistic and think that we must pray long & great prayers for them to be effective)
Short, frequent, and fervent petitions, which will almost necessarily arise from what is felt when temptation is most violent, are best suited to the case....
Blessed be God that we fight with an enemy already vanquished by our Lord, and that we have a sure promise of victory. The Lord is our banner.
