Can society function without a common standard of weights and measures, currency, and time-keeping? Is competition in athletics possible without rules? But what about religion? Is it left up to each person what to believe and practice, or is there a universal standard? There is. God sent Jesus, not only to die as our Savior, but also to reveal an authoritative message for our salvation. Jesus then transferred this message to the apostles. Guided by the Holy Spirit, they in turn preached this message, which is now preserved in the New Testament. This is our standard today.
