Why is it dangerous to rely on past experiences for salvation?

Trusting in past experiences instead of an ongoing relationship with Christ can create a dangerous false sense of security. Salvation is not a one-time event, but a continuous process of repentance and faith. Paul encourages believers to examine themselves regularly (2 Corinthians 13:5) to ensure they are in the faith. If one's relationship with Christ becomes stagnant or based solely on a past emotional experience, they may be deceiving themselves and missing the true essence of salvation, which is active faith in Christ today.
