Continued from here, where Teresa is discussing interior battles with thoughts and passions.

By the blood which our Lord shed for us, I implore those who have not yet begun to enter into themselves, to stop this warfare.

I beg those already started in the right path, not to let the combat turn them back from it.

They should confide in God’s mercy, trusting nothing in themselves; then they will see how His Majesty will lead them from one mansion to another, and will set them in a place where these wild beasts can no more touch or annoy them….

Then, even in this life, they will enjoy a far greater happiness than they are able even to desire….

I have explained elsewhere how you should behave when the devil thus disturbs you.

I also told you that the habit of recollection is not to be gained by force of arms, but with calmness, which will enable you to practise it for a longer space of time.

[…] The only remedy for having given up a habit of recollection is to recommence it, otherwise the soul will continue to lose it more and more every day, and God grant it may realize its danger.

[…] “He that loves danger shall perish by it” (Sirach 3:27) and the door by which we must enter this castle is prayer.

Remember, we must get to heaven, and it would be madness to think we could do so without sometimes retiring into our souls so as to know ourselves, or thinking of our failings and of what we owe to God, or frequently imploring His mercy.

Our Lord also says “No man cometh to the Father but by Me” (John 14:6)…and “He that sees Me sees the Father also” (John 14:9).

If we never look up at Him and reflect on what we owe Him for having died for us, I do not understand how we can know Him, or perform good deeds in His service.

What value is there in faith without works?

And what are they worth if they are not united to the merits of Jesus Christ, our only good?

What would incite us to love our Lord unless we thought of Him?

May He give us grace to understand how much we cost Him;

that “the servant is not above his lord” (Matt. 10:24);

that we must toil for Him if we would enjoy His glory;

and prayer is a necessity to prevent us from constantly falling into temptation (Matt. 26:41).
