Just Jesus
You don’t get to Jesus by studying about God. You actually get to God by following Jesus.
Yes, the Acts of the Apostles are the Acts of the Holy Spirit, but the point of it all is they are the Acts of Jesus.
If you want to learn about the Holy Spirit, immerse yourself in the life of Jesus; in the story and the stories from the gospel accounts.
Fasting does not begin with a lot of how-to’s, but with deep immersion into the story and the stories of Jesus and his disciples fasting.
We must expand our way of praying to include calling out to people in their various challenging life situations in the power of the Spirit.
