Final answer:
The correct answer is 'a) Faith, sins,' which reflects the Christian belief in the significance of the resurrection of Jesus Christ for redemption from sins and the purpose of faith.
Step-by-step explanation:
The correct answer to the question 'If Christ be not raised our ___ is in vain, and we are yet still in our ___.' is a) Faith, sins.
This statement reflects the fundamental Christian belief that the resurrection of Jesus Christ is central to Christianity's doctrine of salvation. According to this belief, if Christ was not resurrected, there would be no redemption from sin, and thus the practice of faith would be without purpose. In this context, without the resurrection, believers would remain in their sins, indicating that the act of redemption through Jesus's sacrifice would be nullified.
The other options such as baptism, guilt, prayer, and transgressions do not fit as appropriately in the context of this particular biblical teaching about the significance of the resurrection of Christ.
