God is perfectly holy, loving, and just, while people are sinful and fall short of God's standards. The penalty for sin is death and separation from God. Jesus lived a sinless life and died on the cross as a substitute for sinners, satisfying both God's love and justice. Eternal life is a free gift received only through believing in Jesus, which involves realizing one's sinfulness, inability to save oneself, and placing one's trust fully in Jesus alone. True belief leads one to receive Jesus into their life.
