Brothers and sisters:
If then you were raised with Christ, seek what is above,
where Christ is seated at the right hand of God.
Think of what is above, not of what is on earth.
For you have died, and your life is hidden with Christ in God.

Epistle of Paul, Letter to Colossians chapter 3

“The kingdom of heaven is to be taken by storm, and it is only the violent that carry it away”. (Matt 12)  And, as when you go against the tide, you must always row without ceasing, and when you stop but for a while, you find yourself drifted far from the spot you had rowed to; so here you must still push forward, and make head against the current of your depraved passions, unless you be content to see yourself quickly carried far back from that degree of perfection which you had before attained. –St Alphonsus Rodriguez ‘The Practice of Christian & Religious Perfection I’.
