In Titus 2:14, the term *katharizo* (G2511) is used to describe the ongoing work of Jesus Christ in purifying a people for Himself. This word means to cleanse from what defiles, making fit for a purpose. It signifies that He is actively removing all sins, bad attitudes, and the influences of human nature and the adversary from His people. Through this cleansing process, He is preparing them to be holy, equal partners with Him in His Kingdom, shaping them into a special people eager to do good works alongside Him for eternity.

The concept of cleansing, as represented by the Greek word *katharizo* (G2511), holds significant importance during the Days of Unleavened Bread, symbolizing the removal of sin from our lives. In I John 1:7, the word *cleanse* is derived from *katharizo* in the aorist or present continuous tense, indicating that the blood of Jesus Christ does not merely cleanse us at the moment of conversion but continues to cleanse us who have been converted. This ongoing process underscores a persistent purification from sin as we strive to walk in the light of God's commandments. Furthermore, in I John 1:9, *katharizo* is used to express that if we confess and repent of sins committed after conversion, Jesus Christ, as our High Priest in heaven, will not only forgive us but also cleanse us from all unrighteousness. This cleansing is an internal purification, aimed at removing the inclination to sin, provided we actively work with Him to overcome it. The continuous nature of this cleansing reflects our ongoing commitment to live according to God's way, ensuring that sin does not separate us from fellowship with Him.

In Luke 17, the concept of cleansing and healing is explored through the parable of the ten lepers, with specific emphasis on the Greek word *katharizo* (Strong's G2511), translated as "cleanse" in verse 14. All ten lepers were physically cleansed of their leprosy, as indicated by this term, showing the initial act of purification performed by Jesus. However, the narrative progresses to distinguish varying degrees of healing and restoration among them. While *katharizo* marks the physical cleansing of all ten, only the Samaritan leper, who returned to give thanks, received something beyond mere physical restoration, setting the stage for a deeper spiritual wholeness. This initial cleansing, denoted by *katharizo*, serves as the foundation for the broader lesson on gratitude and humility in relation to God.
