“This would indeed be neither permissible nor possible, had not God, by virtue of the mysterious interlacing of necessity and freedom in His nature and operations, granted a power to the prayer of faith, to which He consents to yield; had He not… placed Himself in such a relation to men, that He not merely works upon them by means of His grace, but allows them to work upon Him by means of their faith; had He not interwoven the life of the free creature into His own absolute life, and accorded to a created personality the right to assert itself in faith, in distinction from His own.” (Keil & Delitzsch)
