Every Christian must be a living book wherein one can read the teaching of the gospel. This is what Saint Paul says to the Corinthians, 'Clearly you are a letter of Christ which I have delivered, a letter written not with ink, but by the Spirit of the living God, not on tablets of stone but on tablets of flesh in the heart' (2 Corinthians 3:3). Our heart is the parchment; through my ministry the Holy Spirit is the writer because 'my tongue is nimble as the pen of a skillful scribe'(Psalms 45:2).
