No you dont, neither do you understand it ! You dont believe the Gospel, and neither does sproul, he neglected a spiritual truth of the Gospel as it pertains to the spiritually saving death of Christ, all for whom He died were healed 1 Peter 2:24 so that they live unto God 1 Pet 2:24
24 Who his own self bare our sins in his own body on the tree, that we, being dead to sins, should live unto righteousness: by whose stripes ye were healed.
Peter is telling believers why it is they become believers or to live unto Righteousness, because Christ's stripes healed them ! That word healed iaomai means :
I.to cure, heal
II.to make whole
A.to free from errors and sins, to bring about (one's) salvation
To bring about ones salvation means to:
to cause to come into being; make happen ! His stripes caused their Spiritual Salvation to happen, to come into being ! Do you believe that ?
