Faithful Christian living in the everyday might not sound challenging, but, as author and blogger Aimee Byrd shows us, it's actually a real workout! Knowing God takes effort-just like any relationship. Aimee invites us to join her in some theological fitness training as she unpacks our call to perseverance in the book of Hebrews and explores the great metaphor that physical fitness lends to theology. Learn about the "fighting grace" God has given you, discover how you are equipped to live a life of Christ-focused obedience, and get ready to embrace your faith in a fresh, invigorating way.
