Faith is like dry, parched earth that eagerly soaks up the rain that falls on it. Faith is like a hungry newborn craving the pure spiritual milk of its mother. Faith in Christ craves the pure spiritual milk of its mother, holy Church, and the rich forgiveness, life, and salvation that come in the Name of Jesus through the Word preached and through the Sacrament. When Peter preached to the people who were gathered at the temple for evening prayer, he promised refreshment in the Name of Jesus. Repent, therefore, and turn again, that your sins may be blotted out, that times of refreshing may come from the presence of the Lord.
Refreshment here means more than a cold drink on a hot day.
Refreshment means sins forgiven, debts wiped out, our records made clean and spotless on account of Jesus' dying and rising. Peter and John had just healed a man who had been born lame. Paraplegic from birth, he was brought to the temple each day by his friends at the time of the evening sacrifice to beg money from the worshipers. Begging money was not considered dishonorable. If a person could not work, it was considered an honest way to make a living.
