How do I know my heart is truly clean before God?

To ascertain whether our hearts are clean before God, we must first recognize that our natural condition is one of sin and rebellion against Him. As articulated in 1 John 1:8, if we claim to be without sin, we deceive ourselves. A true believer understands that only through Christ's perfect sacrifice can we be considered clean. We rely not on our own works or worthiness, but on the righteousness of Christ imputed to us through faith. Additionally, God grants us a new heart that desires to obey and follow Him, evidencing that true cleansing has taken place.
