Actions speak louder than words; let your words teach and your actions speak. We are full of words but empty of actions, and therefore are cursed by the Lord, since he himself cursed the fig tree when he found no fruit but only leaves. It is useless for a man to flaunt his knowledge of the law if he undermines its teaching by his actions.
But the apostles “spoke as the Spirit gave them the gift of speech.” Happy the man whose words issue from the Holy Spirit and not from himself!
We should speak, then, as the Holy Spirit gives us the gift of speech. Our humble and sincere request to the Spirit for ourselves should be that we may bring the day of Pentecost to fulfillment, insofar as he infuses us with his grace, by using our bodily senses in a perfect manner by keeping the commandments. Likewise we shall request that we may be filled with a keen sense of sorrow and with fiery tongues for confessing the faith so our deserved reward may be to stand in the blazing splendor of the saints and to look upon the triune God.
