Definition and Overview:
Growth in salvation refers to the process of spiritual maturation and sanctification that occurs in a believer's life after accepting Jesus Christ as Lord and Savior. This growth is characterized by an increasing conformity to the image of Christ, a deepening relationship with God, and the manifestation of the fruits of the Spirit. It is a lifelong journey that involves both divine initiative and human responsibility.

Biblical Foundation:
The concept of growth in salvation is rooted in Scripture, where believers are encouraged to pursue spiritual maturity. The Apostle Paul writes in Philippians 2:12-13 , "Therefore, my beloved, just as you have always obeyed—not only in my presence but now even more in my absence—continue to work out your salvation with fear and trembling. For it is God who works in you to will and to act on behalf of His good purpose." This passage highlights the cooperative nature of spiritual growth, where believers actively participate in their sanctification while relying on God's power.

Key Aspects of Growth:

1. Sanctification:
Sanctification is the process by which believers are set apart for God's purposes and progressively transformed into the likeness of Christ. In 1 Thessalonians 4:3 , Paul states, "For it is God’s will that you should be sanctified: that you should avoid sexual immorality." This ongoing transformation involves the renewal of the mind (Romans 12:2) and the putting off of the old self (Ephesians 4:22-24).

2. Fruit of the Spirit:
Spiritual growth is evidenced by the fruit of the Spirit, as outlined in Galatians 5:22-23 : "But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, and self-control." These attributes reflect the character of Christ and are cultivated in the believer's life through the Holy Spirit's work.

3. Knowledge of God:
Growth in salvation involves an increasing knowledge of God and His Word. Colossians 1:10 encourages believers to "walk in a manner worthy of the Lord and please Him in every way: bearing fruit in every good work, growing in the knowledge of God." This knowledge is not merely intellectual but relational, leading to a deeper understanding and love for God.

4. Perseverance:
Spiritual growth requires perseverance through trials and challenges. James 1:2-4 exhorts believers, "Consider it pure joy, my brothers, when you encounter trials of many kinds, because you know that the testing of your faith develops perseverance. Allow perseverance to finish its work, so that you may be mature and complete, not lacking anything." Trials are seen as opportunities for growth and refinement.

5. Community and Discipleship:
Growth in salvation is often fostered within the context of Christian community and discipleship. Hebrews 10:24-25 emphasizes the importance of fellowship: "And let us consider how to spur one another on to love and good deeds. Let us not neglect meeting together, as some have made a habit, but let us encourage one another, and all the more as you see the Day approaching." Believers are called to support and edify one another in their spiritual journeys.

Role of the Holy Spirit:
The Holy Spirit plays a crucial role in the believer's growth in salvation. He convicts of sin, guides into all truth, and empowers for righteous living. In John 16:13 , Jesus promises, "But when He, the Spirit of truth, comes, He will guide you into all truth." The Spirit's indwelling presence is essential for transformation and growth.

Conclusion:
While there is no conclusion in this entry, it is evident that growth in salvation is a dynamic and multifaceted process. It involves a partnership between the believer and God, where the believer actively seeks to grow in faith, knowledge, and holiness, while relying on the Holy Spirit's power and guidance.
