"Looking" on the Old Testament serpent is identical with "believing" on the New Testament Christ. That is, the looking and believing are the same thing...While Israel looked with their external eyes, believing is done with the heart...Faith is the gaze of the soul upon a saving God...Believing, then, is directing the heart's attention to Jesus. It is lifting the mind to "behold the Lamb of God," and never ceasing that beholding for the rest of our lives. ...AW Tozer image
