How do we know true godliness?

True godliness is described as a genuine spirituality granted by the Holy Spirit through the new birth. It involves recognizing one's own sinfulness and the need for Christ's righteousness, which is imputed to believers. This understanding cultivates a desire to obey God's commandments, not out of obligation, but from gratitude for His grace. Thus, a believer's life reflects godliness when it is rooted in the understanding of salvation by grace through faith in Christ alone (Romans 10:3).
