An Unbreakable Covenant recounts the true story of a desperate mothers’ covenant prayer with God for a child. When the family become trapped one night on top of a snow-capped mountain in the wilderness, God sends an angel to rescue his covenant child. He then issues a soul-shaking warning, and leaves behind a mysterious list of Bible verses with divine instructions. Nanette hopes to encourage others by sharing her astonishing story of supernatural intervention, redemption, and revelation that promises to change the world.

The story unfolds after the unwed couple have an abortion. Once they marry, Nanette thinks God is preventing her from getting pregnant, so she does the unthinkable: praying to God for a child, she enters into a covenant prayer. If God gives her a child, then she will give that child back to God. The prayer is then forgotten, but not by Almighty God.

After the birth of their son, the family become stranded at night on a snow-capped mountain trail in the remote Oregon wilderness. Desperate to save her child’s life, Nanette prays again for God's help, and led by the Holy Spirit, is saved by a mysterious man named John Mark.

John Mark recounts how God woke him up in the middle of the night to rescue his covenant child. By listening to God's supernatural instructions, John Mark drove up the deserted, snow-bound logging trail, searching for the covenant child. Seeing only the parents, John continues driving past the family, searching further up the mountain.

Upon finding a baby seat in an abandoned jeep, John returns back down the mountain trail. Moved by the Holy Spirit, the mother opens her coat, revealing the sleeping child into John's headlights, where John Mark finding God's covenant child, and the family is rescued.

John Mark intervenes yet again, soon visiting the family’s remote mountain home to check on the mother and child. After John supernaturally transforms into Jesus, Nanette now stands face-to-face with Christ, incurring his wrath from her long-forgotten covenant prayer with God.

Ashamed and remorseful, Nanette receives judgement from Almighty God. After God issues the mother a soul-shaking warning and, ultimately, redemption, John Mark then leaves behind a mysterious list of Bible verses and divine instructions from God.

From a simple covenant prayer to God's wrath and redemption, the revelation of God's holy instructions have the power to change any believer's life today.
