How do we know the existence of God is true?

The reality of God’s existence can be observed through the natural world; the heavens and firmament continuously testify to His glory and handiwork. This manifestation aligns with Romans 1:20-21 where it highlights that creation speaks to God's eternal power and Godhead. Furthermore, the spiritual mind finds a deep connection and harmony between nature and divine revelation, leading to an overwhelming sense of God's presence. Yet, belief in God must be complemented by the work of the Holy Spirit, who convicts the heart of sin and guides individuals toward the understanding of Christ’s redemptive work.
