Why is the eternal nature of God important for Christians?

The eternal nature of God is foundational in Reformed theology, as presented in Psalm 90, where Moses declares, 'from everlasting to everlasting, thou art God.' This truth assures believers of God's sovereignty over all aspects of existence, including time and creation. Recognizing that God is not bound by time allows Christians to trust in His eternal plan and purpose, fostering faith amidst life’s uncertainties. It also provides comfort in knowing that our lives are part of His unchanging decree, instilling hope in the ultimate fulfillment of His promises throughout eternity.
