"Like the Holy One who called you, be holy yourselves also in all your behavior; because it is written, 'You shall be holy, for I am holy.'" - I Peter 1:15-16
God is faithful. He is mindful of our frail humanity. He created us. He loves us. When he called us to sanctification, to be holy to him, he did so not to discourage us or to give us an impossible command. He called us to be like him so that we could experience his joy to the fullest, his grace to the utmost, his love for all the ages of eternity.
