The Day of Pentecost initiated a miracle of speaking and hearing and washing and eating! Jesus had said it was to our advantage that He go away and send the Holy Spirit (John 16:7). That advantage is immediately seen as His disciples boldly proclaimed the crucified and risen Christ and those who had crucified Him were cut to the heart! That advantage is wondrously seen in God's command to be baptized (washed) for the forgiveness of sins! That advantage is ongoingly seen as the Holy Spirit led the Church in steadfast devotion to the fellowship and the prayers that flowed from and were centered in the Apostle's Teaching and the Lord's Supper (breaking of bread) (Acts 2:42).
What an advantage for you - who have received the washing of rebirth (Titus 3) and been clothed with Christ (Gal 3)! What an advantage for you who have been gifted with faith by the Holy Spirit! What an advantage for you as the risen Christ comes each week to teach you (the Apostle's Doctrine) and to feed you (the breaking of bread)!
The means of the Holy Spirit have not changed since that first Pentecost! He brings Jesus to you with words and water and bread and wine! The gifts He gives you therein carry with them forgiveness of sins, life and salvation! The gifts He gives you carry with them an eternal advantage!
Teach us to know the Father, Son,
And You, from both, as Three in One
That we Your name may ever bless
And in our lives the truth confess.
Praise we the Father and the Son
And Holy Spirit, with them One,
And may the Son of us bestow
The gifts that from the Spirit flow!
