Where do you go when all that once stabilized your spiritual life suddenly shifts underneath you? When your faith is shaken and your leaders fail you? When you're languishing in ministry burnout? When you're grieving a friend who walked away from God? When the doubts, disappointments, and sufferings of this broken world tempt you to walk away from him too?

Author and Bible teacher Courtney Reissig has wrestled with these questions. And when painful circumstances pulled down the trappings of easy Christianity and pushed her back against the wall of her faith, she had to decide. Will I walk away, or will I stay? And if I stay and wade through the rubble, what is left there to believe in?

It is here in the hardest point of her story—in the season where trust was eroded and spiritual stability seemed elusive—where God met her. By opening her eyes to crucial and comforting moments in the Gospel of John, God made it clear: even in the most unstable and changing of times, there is One who stays the same. His name is Jesus Christ, and he's someone to believe in.

If you feel disoriented, doubting, grieving, exhausted, or shaken in your faith, open these pages, and encounter the steadying power of the unchangeable Christ.
