Easter Sunday is an anticipation of Pentecost.

Karl Barth writes of the human response being one of ‘unconditional gratitude…because baptism of the Holy Spirit is the active and actualising grace of God. This is because humanity is now ‘free for decision. A decision that conforms to our liberation’ which has come about in the gift of reorientation handed to us in the life, death and resurrection of Jesus Christ. (Barth, C.D IV.4.1, pp.33-3).
