This is so sweet to my soul, I had to share it with you. May you be blessed as I was!
Saving faith is the hand of the soul. The sinner is like a drowning man at the point of sinking. He sees the Lord Jesus Christ holding out help to him. He grasps it and is saved. This is faith (Hebrews 6:18)
Saving faith is the eye of the soul. The sinner is like the Israelite bitten by the fiery serpent in the wilderness, and to the point of death. The Lord Jesus Christ is offered to him as the brazen serpent, set up for his cure. He looks and is healed. This is faith (John 3:14).
Saving faith is the mouth of the soul. The sinner is starving for food, and sick of a sore disease. The Lord Jesus is set before him as the bread of life, and the universal medicine. He receives it, and is made well and strong. This is faith (John 6:35).
Saving faith is the foot of the soul. The sinner is pursued by a deadly enemy, and is in fear of being overtaken. The Lord Jesus Christ is put before him as a strong tower, a hiding place, and a refuge. He runs into it and is safe. This is faith (Proverbs 18:10)
