We ever have near us an advocate of evil, whether we eat or drink, whether we are asleep or awake, even our own flesh, the old Adam. He accompanies us to bed and arises with us in the morning; he pleads unceasingly and eloquently, with the fixed purpose of estranging us from Christ and His Gospel. This advocate of evil whom we constantly carry about with us, and whose habitation is in our hearts, is ever intent on exciting us to become rich and great in the world, and sways us with the delusion that we have neither occasion nor time to go to the Sacrament. If we heed his lying counsels we will grow colder and colder in our love towards Christ and His gifts; yea, though we might even daily hear His word, this cunning tempter within us will bring it to pass that we do so merely outwardly, while in reality our devotion is a sham, and our thoughts are engaged with the business of this world. Show me the avaricious man who grows weary of his passion! Is it not rather time that the covetous man becomes fonder and fonder of his idols from day to day, cherishing and pursuing with eagerness avarice and usury? The same is true in regard to other sins. The lewd person delights in his unchastity; he thinks and speaks about it with evident glee, and indulges in his wicked passion more and more. Such are the results of the instructions which the old Adam gives: they lead to destruction.
Christ desires to counteract the sinister influence of the old seducer within us, who would fix our attention alone and chiefly on temporal things. Christ instead would have us he mindful of eternity, of Himself, our Saviour, who died for us upon the cross. He would fain have us see our foolishness, so that we would gladly come unto Him, weary of our depraved life exclaiming: O Lord, we know how sinful we are, and how unable to resist the allurements of evil, therefore we cry unto Thee for help; enable Thou us to shun the world and to love Thee truly. We stand in daily need of such remembrance of Christ in opposition to this pernicious advocate, this old Adam within us, who clamors about our ears day and night, hoping to plunge us, beyond all help, into the cares and pleasures of this world.
