The Spirit is God's greatest gift, and He is given in order to restore and refresh us. 1. Know about the grand gift, and celebrate. (v.1-4) 2. Evaluate the mixed reactions, and keep them in mind. (v.5-13) 3. Understand Peter's explanation, and call on God. (v.14-21) How does this apply to us? What do we know about the power of the Spirit? Ezekiel 37:9-14 Who may call on the name of the Lord? Romans 10:9-13 Who says not to harden our hearts? Hebrews 3:7-12
