There is power in God's Word. In Psalm 119:9-10 it says, "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!"
In these two verses are the answers to whether a person can experience God's cleansing. Also here is the process by which cleansing is possible. He asks the question, "How can a young man cleanse His way?" The only possible answer is "By taking heed according to Your Word."
Do you heed the Word of God? If you don't, you are far from having your way cleansed. Instead you are walking in the filth of disobedience. Obey God's Word today and have your way cleansed.
