What must I know for God to save me?

To be saved, it is essential that one is known by God and has faith in Christ. As the sermon points out, our natural state is one of ignorance concerning divine matters (Romans 3:11, 1 Corinthians 2:14). However, 1 John 4:19 encapsulates the core of this doctrine, stating, 'We love him because he first loved us.' This implies that salvation is not contingent on what we know or understand, but rather on God's initiative in knowing and loving us first, prompting our faith in Jesus Christ.
