The Spirit of God is the Spirit of Prayer. He inspires it, He sustains it, He works in us, on us and around us in response to it. It's His power which aligns our prayers with Abba's will and sets them firmly on the ground of being answered affirmatively in God's good Time.

Apart from the Spirit of Jesus, prayer is often just ...a lot of hot air. LOL So, as Paul and Jude enjoin us, "pray at all times in the Spirit."
