“If you address as Father the One who impartially judges according to each one’s work, conduct yourselves in fear during the time of your stay on earth…” (1 Peter 1:17).
To experience and manifest God’s holiness in our lives, we need to renew our minds (Romans 12:1-2) through God’s Word.
Christians are already holy through faith in Jesus. We need to learn how to live out that holiness.
Following rules does not make somebody holy. Holiness means to be set apart. People and objects become holy as they are set apart for God’s glory.
