So what should our final preparations be?
Firstly a recognition that this is God's work; not ours. The primary witness to the resurrection of Jesus is the Holy Spirit. The rest of us are secondary witnesses. Without Him we can do nothing.
Secondly a willingness to let the Holy Spirit surprise us; an openness to Him working in unexpected ways that might initially make us feel uncomfortable.
Thirdly, and most importantly, total surrender to Him. What does this consist of? What does it look like? Putting all your hopes and dreams and plans in God's care, and being happy if none of them come to pass - as long as God's will is done in us and through us. At the beginning of the rite of ordination to the priesthood, the candidates come forward, and lay down prostrate on the floor to symbolise that they are giving themselves completely to God for His purposes, and the renunciation of everything of their own will in favour of His.
Our model and our hope in these final preparations is the mother of Jesus. With her assistance what is most difficult becomes easier, and whatever obstacles there are decrease and dissolve. May her intercession obtain for us the grace of complete co-operation with the Holy Spirit. Amen.
