What does the Bible say about holding fast to the gospel?

In 2 Timothy 1:13-14, Paul encourages Timothy to 'hold fast the form of sound words' which he has received in faith and love. This call to 'hold fast' is akin to the commitment seen in the union of marriage, emphasizing the need for believers to be deeply devoted and dedicated to the truths of the gospel. The sound words refer to the central doctrines of salvation and grace through Christ. They should be cherished, not taken for granted, as they reflect God's enduring purpose and love toward us. Paul’s exhortation stands as a reminder that the gospel is not merely a collection of beliefs but a profound commitment that shapes our life and ministry.
