What can all this mean except that we have in our hearts organs by means of which we can know God as certainly as we know material things through our familiar five senses? We apprehend the physical world by exercising the faculties given us for the purpose, and we possess spiritual faculties by means of which we can know God and the spiritual world if we will obey the Spirit’s urge and begin to use them.

That a saving work must first be done in the heart is taken for granted here. The spiritual faculties of the unregenerate man lie asleep in his nature, unused and for every purpose dead; that is the stroke which has fallen upon us by sin. They may be quickened to active life again by the operation of the Holy Spirit in regeneration; that is one of the immeasurable benefits which come to us through Christ’s atoning work on the cross.
