Have courage and do not fear the assaults of the Devil. Remember this forever; it is a healthy sign if the devil shouts and roars around your conscience, since this shows that he is not inside your will.
Do not let temptations frighten you; they are the trials of the soul whom God wants to test when He knows that he is strong enough to sustain the battle and weave his garland of glory with his own hands.
St. Pius of Pietrelcina (Padre Pio)
Be strong and of good courage, fear not, nor be afraid of them: for the LORD thy God, he it is that doth go with thee; he will not fail thee, nor forsake thee.
The LORD our God be with us, as he was with our fathers: let him not leave us, nor forsake us: That he may incline our hearts unto him, to walk in all his ways, and to keep his commandments, and his statues, and his judgments, which he commanded our fathers.
1 Kings 8:57-58
