“For Satan has no method more effectual for ruining the salvation of the godly, than by dissuading them from calling on God. For this reason, he employs his agents to drive off from us, as far as he can, the desire to pray.”
John Calvin and William Pringle, Commentary on a Harmony of the Evangelists Matthew, Mark, and Luke, vol. 3 (Bellingham, WA: Logos Bible Software, 2010), 320.
