You may think that you will be full of determination to resist outward trials if God will only grant you inward favours. His Majesty knows best what is suitable for us; it is not for us to advise Him what to give us, for He can rightly reply that we know not what we ask.46 All that the beginner in prayer has to do -- and you must not forget this, for it is very important -- is to labour and be resolute and prepare himself with all possible diligence to bring his will into conformity with the will of God. As I shall say later, you may be quite sure that this comprises the very greatest perfection which can be attained on the spiritual road. The more perfectly a person practises it, the more he will receive of the Lord and the greater the progress he will make on this road; do not think we have to use strange jargon or dabble in things of which we have no knowledge or understanding, our entire welfare is to be found in what I have described. If we go astray at the very beginning and want the Lord to do our will and to lead us just as our fancy dictates, how can this building possibly have a firm foundation? Let us see that we do as much as in us lies and avoid these venomous reptiles, for often it is the Lord's will that we should be persecuted and afflicted by evil thoughts, which we cannot cast out, and also by aridities; and sometimes He even allows these reptiles to bite us, so that we may learn better how to be on our guard in the future and see if we are really grieved at having offended Him.
