Just as it is necessary to take a bath periodically to cleanse our bodies of dust, dirt and grime and for refreshment we need to have regular spiritual cleansing.
Psalm 119:9 Wherewithal shall a young man cleanse his way? by taking heed thereto according to thy word.
We need to read, hear, know the Word to have have our hearts, minds and spirits cleansed so that we keep clean in body, soul and mind with clean conscience , and joyful heart, living and pleasing the Lord in obedience to Hiis Word. When we repent of what is wrong in our hearts and lives, He cleanses us by the blood of the Lamb. Keeps and refines us by His Holy Spirit and Word.
