Grace & the Power of the Holy Spirit

A little bit of Jesus can lead to Grace, but if the right conditions apply. The power of the Holy Spirit gives us strength but is there more? We see a battle between good and evil on a daily basis. We see in scripture the power throughout the Old and New Testaments. Why do we not have that power? The difference is faith and boldness. We talk about persecution, but they lived a life and death scenario every day for their faith.
