"[H]e must rise again" †The Resurrection meant New Life for Christ as Man. He lived again after death, with a body that still bore the scars, but manifested new, glorious properties. He could enter rooms that had the doors shut, for example "And after eight days again his disciples were within, and Thomas with them: then came Jesus, the doors being shut, and stood in the midst, and said, Peace be unto you." John 20:26, just appearing.
But what about us?
However, unlike the divine and sinless Jesus we cannot produce it from within, we cannot manufacture this new life by our own efforts or earn it by our deeds. It must be received freely. It is a gift.
How do we receive it, then?
But then what?
Living, penitent faith remains the foundation. In other words, faith in Christ is not just a beginning, it is a pathway, the ongoing condition/prerequisite of all progress.
The Word of God.
(Note how Church helps with prayer and Scripture! We need its guidance, we were never meant to live in isolation as Christians.)
And give thanks for his wonderful gift, the Resurrection Reality, increasing in it through prayer, the Bible, the Church and good works. †
