How can a young man cleanse his way?
By taking heed according to Your word.
With my whole heart I have sought you.
Oh, let me not wander from your commandments!
Your word I have hidden in my heart,
That I might not sin against You.
Blessed are You, O LORD!
Teach me Your statutes.
With my lips I have declared
All the judgements of Your mouth.
I have rejoiced in the way of your testimonies,
As much as in all riches.
I will meditate on your precepts,,
And contemplate Your ways.
I will delight myself in your statutes;
I will not forget Your word.

This writer is really concerned about living God’s way. How do I cleanse my way? I wash myself daily, hourly, in God’s Word. I wash everything I read, everything I see, everything I hear, everything I do, in the cleansing Word of God. Specifically, I think about these things that make up my life in the light of Scriptural principles. How does this or that square with what God has said? I hide His word in my heart, memorize it; I declare it with my lips, speak truth in love; I meditate on God’s guidance, and I contemplate His ways. Then I can delight myself in God’s law and not forget His word.

Lest anyone think this joyful discipline of studying and applying God’s Word to our lives is optional, esoteric speculation, WORLD magazine’s blog gives this example of a man who did not cleanse his way:

And now it turns out that convicted child-molester Joseph Duncan, arrested for kidnapping that little girl in Idaho and the suspect in the murder of her family, talks about his struggle with demons on his blog. “God has shown me the right choice,” he wrote, “but my demons have me tied to a spit and the fire has already been lit.” And then, in one of his last entries, “The demons have taken over.”

“He has shown you, O man, what is good;
And what does the Lord require of you
But to do justly,
To love mercy,
And to walk humbly with your God?”
Micah 6:8
