How do we know that salvation in Christ is true?

The truth of salvation in Christ is based not merely on human understanding but is rooted in God's revelation through Scripture and the work of the Holy Spirit. Romans 10:10 states, 'For with the heart one believes and is justified, and with the mouth one confesses and is saved.' This indicates that true faith involves an internal conviction of the heart, which is further confirmed by the Holy Spirit's work in our lives. Through the gospel message, believers come to know their salvation is assured, and their conscience is purged from guilt, enabling them to live boldly for Christ.
