God reveals Himself to humanity through His righteousness, wrath against ungodliness, basic truths, and His invisible attributes made visible through creation. The Gospel message emphasizes our need for salvation and Jesus Christ's offer of salvation through faith. People often suppress these truths due to a preference for personal autonomy and sin's destructive nature. When we reject God's truth, we experience darkened understanding, futile thinking, and spiritual blindness. The path to righteousness comes through faith in Jesus Christ, not through personal efforts.
