What wonderful joy and hope these scriptures should inspire in our hearts! What confidence in trial and tribulation! These words tie the certainty of future events to the past accomplishments of the cross and resurrection. Jesus had all of these future accomplishments of His death already in His mind when He spoke the words "It is finished" on the cross. From heaven's perspective, these works yet to be revealed in our future are already past victories in terms of their completion.
The accomplishments of Christ's passion we're considering are staggering in their power and benefit. They ensure our future, and without a future there is no ultimate meaning to the present. So these two blessings of the passion define who we are because they define where we are going.
