Assurance that Christ died for an individual comes from the acknowledgment of faith in His righteousness and the transformation evident in one's life.
To know whether Christ died for us requires an understanding of the nature of His atonement and the individual's response to it. According to Scripture, particularly in 2 Corinthians 5:14, we learn that Christ's atoning death was intended for His people, which assures believers of their standing in Him. The conviction of the Holy Spirit, leading to faith, is the catalyst that allows individuals to recognize their need for Christ's sacrifice and to understand that they are included among those for whom He died.
Furthermore, the condition of being a new creation, mentioned in 2 Corinthians 5:17, is evidence that Christ died for a person. This transformation implies that the believer no longer lives for themselves but for Him who died and rose again. An outward sign of this inward change is a growing trust in Christ's righteousness rather than personal merit, reflecting a heart that has been changed by God's grace.
