Eph 1:7 In Him we have redemption through His blood, the forgiveness of our trespasses, according to the riches of His grace
1Pe 1:18 knowing that you were not redeemed with perishable things like silver or gold from your futile way of life inherited from your forefathers, 19 but with precious blood, as of a lamb unblemished and spotless, the blood of Christ.
Why don't the oneness Pentecostals believe in the sufficiency of the blood of the Lamb?
