When you stop praying, you're telling the Holy Spirit you don't need help. The speaker argues that constant prayer trades your weakness for God's strength and gives you daily guidance and foresight that you can't get any other way.
Chapters
A day without prayer is to say to the Holy Spirit, I don't need your help today. A week without prayer is to say to the Holy Spirit, I don't need your assistance this week. A life without prayer is to say to the Holy Spirit, I can live in my own strength. I can do it by my own power. I can figure it out in my own intellect. But when you live a lifestyle of prayer, you are inviting the influence of the Holy Spirit, you are trading your weakness for his strength. You're trading your insight for his insight, and he begins to guide you and empower you. What advantage that is in life, that the one who can see the future and knows the hearts of the people around you will speak to you on a daily basis, will guide you as you go. Prayer is essential to the life of every believer.
