Jesus:
My child, every time you commit sin, you are being bitten by the serpent who tries to poison your soul and to destroy it. It is only by my Precious Blood, that you can cleanse your soul once again. The just man falls seven times a day; let us make sure that when you fall you don’t fall into mortal sin. Crush the head of the serpent by rejecting his temptations, and be very quick to confess your sins with contrition when you sin. Human nature is sinful and as a result you sin; even if you try not to. But this will keep you humble in my sight because I am holy, sinless and perfect; and you acquire your holiness when you overcome the world, the devil and the flesh, and when you overcome temptation with virtue. You have been given free will to say no to sin and yes to God.
