The chief way whereby we walk with God is by faith, and not by sight. Abraham walked in this way. Unbelief severs the soul from God. There is no communion between God and an infidel. An unbelieving heart has no fellowship with the Lord Jesus Christ; but a believing heart has communion with him. It is by faith that we have fellowship with God and his dear Son; and you will find that just in proportion to the strength or weakness of your faith is your walking with God.
If you have faith in blessed exercise, as you look to the atoning blood, you find that you can walk with God; you can pour out your heart before him, tell him all your concerns, spread before him the inmost movements of your mind, and look to him for peace and consolation. But when your faith is weak, when it gives way under trial, and cannot take hold of the promises, then communion is interrupted; there is no longer a walking with God. But in proportion as faith is strong, so there is a walking with God in sweet agreement; for faith keeps eyeing the atonement; faith looks not so much to sin, as to salvation from sin; at the way whereby sin is pardoned, overcome, and subdued. So it is by faith, and in proportion to our faith, that we walk together with God.
