The Bible provides numerous instructions on the nature and quality of associations that believers should maintain. These instructions are rooted in the desire for believers to live lives that are holy, edifying, and reflective of God's character. The Scriptures emphasize the importance of choosing associations that encourage spiritual growth and moral integrity.

1. Association with Fellow Believers

The New Testament underscores the importance of fellowship among believers. Hebrews 10:24-25 states, "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." This passage highlights the necessity of regular fellowship for mutual encouragement and spiritual growth.

Acts 2:42 describes the early church's commitment to community: "They devoted themselves to the apostles’ teaching and to the fellowship, to the breaking of bread and to prayer." This devotion to communal life is presented as a model for believers, emphasizing the importance of shared faith and practice.

2. Caution Against Unequal Yoking

The Bible warns against forming close associations with those who do not share the same faith. 2 Corinthians 6:14-15 advises, "Do not be unequally yoked with unbelievers. For what partnership can righteousness have with wickedness? Or what fellowship does light have with darkness? What harmony is there between Christ and Belial? Or what does a believer have in common with an unbeliever?" This instruction is often interpreted as a caution against forming binding relationships, such as marriage or business partnerships, with those who do not share a commitment to Christ.

3. Influence of Companions

Proverbs 13:20 offers wisdom on the influence of companions: "Walk with the wise and become wise, for a companion of fools suffers harm." This proverb underscores the impact that one's associations can have on personal character and decision-making. The implication is that believers should seek the company of those who exhibit wisdom and godliness.

1 Corinthians 15:33 further warns, "Do not be deceived: 'Bad company corrupts good character.'" This admonition serves as a reminder that associations can have a profound effect on one's moral and spiritual life.

4. Love and Witness to All

While the Bible advises caution in forming close associations with non-believers, it also commands love and witness to all people. Jesus' example in associating with tax collectors and sinners (Matthew 9:10-13) demonstrates the balance between maintaining personal holiness and engaging with the world in love and truth. Believers are called to be "the salt of the earth" and "the light of the world" (Matthew 5:13-14), indicating a responsibility to influence the world positively while maintaining distinctiveness in character and conduct.

5. Restoration and Accountability

Galatians 6:1-2 provides guidance on how believers should interact with those who have fallen into sin: "Brothers, if someone is caught in a trespass, you who are spiritual should restore him with a spirit of gentleness. But watch yourself, or you also may be tempted. Carry one another’s burdens, and in this way you will fulfill the law of Christ." This passage emphasizes the importance of accountability and restoration within the community of believers, highlighting the role of associations in spiritual growth and healing.

In summary, the Bible's instructions on association encourage believers to seek relationships that foster spiritual growth, exercise caution in forming close ties with non-believers, and maintain a loving and redemptive presence in the world. These principles are designed to help believers navigate their social interactions in a way that honors God and promotes personal and communal holiness.
