The collect this day begins with the attribute of the the Lord's mercy (misericordiae tuae, Domine). Next comes our petition, that God would hear the prayers of his supplicants that come before him (supplicum vota perveniant;). Following this is the expected result -- in order that we might receive that which we beg, that he would grant that we always ask what is acceptable to him (quae poscimus, fac, nos semper tibi placita postulare). Finally the prayer concludes though our Lord Jesus Christ.
LORD, I cry unto thee: make haste unto me; give ear unto my voice, when I cry unto thee.
Let my prayer be set forth before thee as incense; and the lifting up of my hands as the evening sacrifice.
Set a watch, O LORD, before my mouth; keep the door of my lips. [Ps 141:1-3]
The appointed epistle has a very specific application and compliments today's collect. Paul gives stern warning about conduct -- and by way of inference -- the murmurings of our hearts: Lust not after that which is evil (see how Paul defines that evil). "Let him that thinketh he standeth take heed, lest he fall" [1 Cor 10:12]
Ensure that your prayers are in accord with his Word, and seek his aid in prayer. "He that turneth away from his ear from hearing the law, even his prayer shall be abomination" [Proverbs 28:9]
