The phrase "established in the faith" refers to a state of spiritual maturity and steadfastness in one's Christian beliefs and practices. This concept is rooted in the New Testament, where believers are encouraged to grow in their faith and remain firm in their commitment to the teachings of Jesus Christ.

Biblical Foundation

The Apostle Paul frequently addresses the importance of being established in the faith in his epistles. In Colossians 2:6-7 , Paul writes, "Therefore, just as you have received Christ Jesus as Lord, continue to walk in Him, rooted and built up in Him, established in the faith as you were taught, and overflowing with thankfulness." Here, Paul emphasizes the necessity of being deeply rooted in Christ, which leads to being established in the faith. This establishment is not a passive state but an active process of growth and gratitude.

In 1 Thessalonians 3:2-3 , Paul sends Timothy to the Thessalonian church "to strengthen and encourage you in your faith, so that none of you would be shaken by these trials." This passage highlights the role of encouragement and support from fellow believers in becoming established in the faith, especially during times of trial and persecution.

Characteristics of Being Established in the Faith

1. Rooted in Christ: As seen in Colossians 2:7, being established in the faith involves being deeply rooted in the teachings and person of Jesus Christ. This foundation is essential for spiritual growth and stability.

2. Sound Doctrine: A key aspect of being established in the faith is adherence to sound doctrine. In Titus 1:9 , Paul instructs church leaders to "hold firmly to the trustworthy message as it has been taught, so that by sound teaching he will be able to encourage others and refute those who contradict it." Sound doctrine serves as a safeguard against false teachings and helps believers remain steadfast.

3. Perseverance: James 1:12 states, "Blessed is the man who perseveres under trial, because when he has stood the test, he will receive the crown of life that God has promised to those who love Him." Perseverance through trials is a hallmark of being established in the faith, demonstrating a deep trust in God's promises.

4. Community Support: The early church exemplified the importance of community in establishing believers in the faith. Acts 2:42 describes how "they devoted themselves to the apostles’ teaching and to the fellowship, to the breaking of bread and to prayer." Fellowship with other believers provides encouragement, accountability, and mutual edification.

5. Spiritual Maturity: Ephesians 4:14-15 encourages believers to "no longer be infants, tossed about by the waves and carried around by every wind of teaching and by the clever cunning of men in their deceitful scheming. Instead, speaking the truth in love, we will in all things grow up into Christ Himself, who is the head." Spiritual maturity is a sign of being established in the faith, marked by discernment and a Christ-like character.

Practical Application

To be established in the faith, believers are encouraged to engage in regular study of Scripture, prayer, and participation in the life of the church. These practices help to deepen one's understanding of God's Word and foster a closer relationship with Him. Additionally, believers are called to live out their faith through acts of love and service, reflecting the character of Christ to the world around them.

In summary, being established in the faith is a dynamic and ongoing process that involves a firm foundation in Christ, adherence to sound doctrine, perseverance through trials, support from the Christian community, and the pursuit of spiritual maturity.
