One of the amazing part of God's plan for the coming of the Holy Spirit into our lives is that it is not meant to be a  one time experience, like Baptism and Confirmation. The Apostles, Mary and the one hundred and twenty received the anointing of the Spirit at Pentecost for the purpose of proclaiming the Good New of God's love through the death and resurrection of Jesus. A short time later, as the Church began to experience the initial persecution by the religious leaders, the community of believers in Acts 4 responded by praying for a fresh outpouring of the gifts of Spirit, especially boldness. It says all were filled with the Holy Spirit, just as they were on Pentecost. What is the message? We should be praying regularly for a fresh outpouring of the gifts of the Spirit, so that we can more effectively witness our faith to others with signs and wonders as our credentials.  Come, Holy Spirit, come and stir up your gifts within me.
