What does the Bible say about staying in Christ?

Staying in Christ is crucial for believers as the entirety of our salvation is found in Him. Paul, in his epistle to the Galatians, stresses the significance of adhering to the gospel he preached, which centers on Jesus Christ. In Galatians 1:1, he asserts his authority as an apostle, emphasizing that he proclaims the good news of salvation through Christ alone. By remaining in Christ, believers experience not just a bond of faith but also the assurance of justification and grace, as advocated throughout the New Testament.
