How do we know that abiding in Christ is true evidence of salvation?

According to the preaching, abiding in Christ serves as the only true evidence of salvation. This concept illustrates that genuine faith is demonstrated through a persistent relationship with the Lord. Like Ruth who depended on Boaz for both sustenance and security, Christians are called to rely on Christ alone, recognizing that outside of Him, there is no hope. The biblical narrative shows that many may exhibit initial signs of faith, but true conversion manifests in a lifetime of faithfulness and commitment, as affirmed in John 15, where Jesus highlights that those who do not remain in Him will face dire consequences.
