“Blessed are the undefiled in the way,
who walk in the law of the LORD.
Blessed are they that keep His testimonies,
and that seek Him with the whole heart.
They also do no iniquity: they walk in His ways.”
Those who obey God do not sin. God’s way is called the “perfect law of liberty” because obeying it makes us perfectly free from sin. Walk in the law of the LORD; keep His testimonies; seek Him with your whole heart. Doing these things, you will not – cannot – sin.
