Please notice this, the brazen serpent had no venom of itself, but it took the form of a serpent. Christ is no sinner, and in Him is no sin. So, the brazen serpent was in the form of a serpent. When people came to be healed, they only had to look. Man through Adam and Eve became sinners by a look.
Christians continue to look.
At the end of the Christian's life, we are still looking. We are looking for the blessed hope of our Savior's return. Now, friend, from first until last, from the beginning to the end, we are to look to the Saviour for salvation and righteousness. Charles Haddon Spurgeon's conversion is a unique story. Instead, he made his way down the street to the primitive Methodist chapel where a layman filled in for the regular pastor.
