When you want to make a beginning of a good deed, first prepare for temptations, which will come to you, and don't doubt the truth of that which you do for God.
Isaac of NinevehIn all things that you find in the Holy Scriptures, seek out the purpose of the words, that you may enter into the depth of the thoughts of the saints and understand them with greater exactness. Do not approach the reading of the Divine Scriptures without prayer and asking the help of God. Consider prayer to be the key to the true understanding of that which is said in the Holy Scriptures.
Isaac of NinevehWithout temptations, it is not possible to learn the wisdom of the Spirit. It is not possible that Divine love be strengthened in your soul. Before temptations, a man prays to God as a stranger. When temptations are allowed to come by the love of God, and he does not give in to them, then he stands before God as a sincere friend. For in fulfilling the will of God, he has made war on the enemy of God and conquered him.
