Paul is speaking to a young pastor Titus about the renewing of the Holy Spirit specifically in Titus 3:5 however, we need to keep it in contrast and address 3:4-7 as well.

In this section, Paul presents a number of images demonstrating God’s provision of salvation through Christ: washing (purity and cleansing), regeneration and renewing (a new birth), justified (being declared righteous), heirs (receiving an inheritance), and hope (a certain future). Salvation motivates and empowers people to live godly lives. 

Salvation depends on God’s mercy, not our good deeds. All three members of the Trinity – Father, Son, and Holy Spirit – are active in this work. The washing of regeneration is a metaphor for spiritual cleansing through the Holy Spirit. (Ezek 36:26; 1 Cor. 6:11; Eph. 2:4-90. This is symbolized by baptism.

In Titus 3:5, Paul speaks about the concept of renewal in the context of salvation and God's mercy. Here's the verse for context:

> "He saved us, not because of works done by us in righteousness, but according to his own mercy, by the washing of regeneration and renewal of the Holy Spirit."

In this passage, Paul emphasizes that salvation is not achieved through our own righteous deeds but through God's mercy. The "washing of regeneration" refers to the cleansing and rebirth that comes through faith in Christ. The "renewal of the Holy Spirit" highlights the transformative work of the Holy Spirit in a believer's life.

This renewal is an ongoing process where the Holy Spirit continually works within us to transform our hearts and minds, making us more like Christ. It's a reminder that our spiritual growth and renewal are not based on our efforts alone but are the result of God's grace and the work of the Holy Spirit.

How is renewing of the Holy Spirit accomplished?

The renewal of the Holy Spirit is a transformative process that involves several key aspects:

1. Faith in Christ: The journey begins with faith in Jesus Christ. Accepting Him as Lord and Savior opens the door for the Holy Spirit to work in your life.
2. Baptism: Baptism is often seen as a symbolic act of washing away the old self and being reborn into a new life in Christ. It signifies the beginning of the renewal process.
3. Prayer and Meditation: Regular prayer and meditation help you stay connected to God and open your heart to the Holy Spirit's guidance and transformation.
4. Reading Scripture: Engaging with the Bible allows the Holy Spirit to speak to you through God's Word. It provides wisdom, encouragement, and direction for your life.
5. Obedience to God's Will: Following God's commandments and seeking to live according to His will allows the Holy Spirit to work more effectively in your life. Obedience fosters spiritual growth and renewal.
6. Repentance and Confession: Regularly confessing your sins and seeking God's forgiveness helps to cleanse your heart and mind, making room for the Holy Spirit's renewing work.
7. Fellowship with Believers: Being part of a faith community provides support, encouragement, and accountability. It allows you to grow together with others who are also being renewed by the Holy Spirit.
8. Service and Ministry: Serving others and participating in ministry activities can be powerful ways to experience the Holy Spirit's renewal. It helps you to live out your faith and see God's work in action.
9. Continuous Learning and Growth: The renewal of the Holy Spirit is an ongoing process. Continuously seeking to grow in your faith, understanding, and relationship with God allows the Holy Spirit to keep transforming you.

The renewal of the Holy Spirit is a dynamic and lifelong journey. It's about allowing the Holy Spirit to work within you, transforming your heart, mind, and actions to align more closely with God's will. 

Stay strong and keep your eyes on the prize and come to truly understand the price that has been paid by Jesus so that you will someday be in heaven with our Lord and Savior.
