what does the bible say?
Faith in God and His Son, Jesus, is critical to salvation. We learn that without faith, we are unable to please God (Hebrews 11:6) and are taught that only those who believe in God’s Son, Jesus, will be saved (John 3:16). Indeed, salvation rests on the belief that God raised Jesus from the dead (Romans 10:9–10), implicitly requiring belief in God. Ultimately, we owe our existence to God (Genesis 1:26–27; Acts 17:28). But because of sin, our relationship with Him was broken, and we are His enemies (Romans 5:10). His judgment against rebellious humanity is His eternal wrath (Revelation 20:14–15). However, out of mercy, He sent Jesus to provide one way of escape from His wrath (John 14:6), and to crush Jesus in the place of sinners (Isaiah 53:5–6, 10). God is the one who saves, and grants that salvation only to those who express faith in His Son (Ephesians 2:8–9). To not believe in the existence of God means one does not understand salvation. Therefore, one cannot be saved while also not believing that He exists.
