We can be saved, but still not receive the empowerment of the Holy Spirit. God has many gifts for us not just one, and wants us to eagerly seek them out. We're very good at putting God in a box, but He cannot be contained. If we who are evil can bless our children, how much more will our Father give us if we just ask? We need God's power!
Who we are We do not have to do anything spectacular, we just have to put our faith in Jesus. Jesus is the same throughout the ages. The main elements of our faith are to affirm conviction that the word of God is true, this will cause a personal surrender to Jesus, which then is reflected in our conduct.
