“St. Cyprian says, that the divine mercy is an inexhaustible fountain. They who bring vessels of the greatest confidence, draw from it the greatest graces Hence the Royal Prophet has said: ‘Let thy mercy Lord be upon us, as we have hoped in thee.’ (Ps. xxxii. 22.) Whenever the Devil terrifies us by placing before our eyes the great difficulty of persevering in the grace of God in spite of all the dangers and sinful occasions of this life, let us, without answering him, raise our eyes to God, and hope that in his goodness he will certainly send us help to resist every attack. ‘I have lifted up my eyes to the mountains, from whence help shall come to me.’ (Ps. cxx. 1.) And when the enemy represents to us our weakness, let us say with the Apostle ‘I can do all in him who strengtheneth me.’ (Phil. iv. 13 ) Of myself I can do nothing; but I trust in God, that by his grace I shall be able to do all things.”—St. Alphonsus de Liguori, Sermon for the 4th Sunday in Advent (from his published Sunday Sermons for the Year)
