We must prepare ourselves for the coming of the righteous Moshiach

Wrote the Chafetz Chaim (Rabbi Israel Meir Kagan): "We must prepare ourselves with all our might for the coming of the righteous Moshiach, each person according to his ability...so that we merit the complete and true redemption and so that we are able to greet Moshiach joyfully. And whoever doesn't listen to these words, it's his responsibility, and in the future he will be judged, G-d forbid, for then it will be made clear, known and publicized concerning each person, who prepared himself for his [Moshiach's] coming and how he prepared himself, with Torah learning and good deeds, and who did not prepare himself.
