The divine filiation

Baptism confers the gift of divine filiation. It restores humans to their state of friends of God by erasing the original sin of the soul, although its effects are still part of human nature, especially the tendency to do evil. God performs a new birth in our souls, making human His adopted child by transmitting to them His own life (the sanctifying grace).

The baptised are children of God in His Son Jesus Christ, because, by accepting to die on the Cross, He freed humans from the "bondage to decay (i.e. sin) and brought (them) into the freedom and glory of the children of God." (Romans 8,21). 

'Father', said that big fellow, a good student at the university (I wonder what has become of him), 'I was thinking of what you told me — that I'm a son of God! — and I found myself walking along the street, head up, chin out, and a proud feeling inside... a son of God!'
With sure conscience I advised him to encourage that 'pride.' - (The Way, n°274). 

The spirit of the Opus Dei is radically optimistic, it is grounded in trusting in God, on good days as much as on bad days.

Let's pray with saint Josémaria Escriva

 (in Salvador Bernal, His Grace Escriva de Balaguer, Portrait of the founder of the Opus Dei)

I adore the Father, the Son, the Holy Spirit, one God. I do not understand the wonderful nature of the Trinity ; but You made my soul thirsty, hungry to believe. I believe ! I want to believe as much as the most fervent believer. I hope ! I want to hope as much as the most hopeful man !

I love ! I want to love as much as the most loving follower. You are the One who is : the Supreme Good. I am who I am : the last rag napkin of this rotten world. Yet You look at me, You look for me... and You love me. 

Oh Lord, may my children look at You, look for You, and love You.
Oh Lord, how I look for You, how I look at You, oh how I love You !
