This question is a perennial question. Concerned people asked this several times in the book of Acts, and many ask it today. When one asks, “What must I do to be saved?” let us allow the Lord to answer the question.
To be saved, one must believe in Christ. Jesus said, “if ye believe not that I am he, ye shall die in your sins” (John 8:24). This faith (trust) that Christ is God’s Son comes through hearing God’s word (Romans 10:17). Without faith, it is impossible to please God (Hebrews 11:6).
