How can a young man cleanse his way?
By taking heed according to your word.
As modern-day disciples of the Lord, we must study the Word of God daily for spiritual correction, spiritual counsel, and spiritual warfare. The more we read the Word of God, the more His principles of righteousness are inculcated. Moreover, no person can be guided by the Spirit who is not a Bible-mastered man or woman. Also, just like Jesus did in the wilderness, we have to use the Word of God as our weapon against the Enemy of our souls.
