45. Question: How does Christ's resurrection benefit us?
Answer: First, by His resurrection He has overcome death, so that He could make us share in the righteousness which He had obtained for us by His death. Second, by His power we too are raised up to a new life. Third, Christ's resurrection is to us a sure pledge of our glorious resurrection.
