How do we know Jesus's mercy is available to all sinners?

In John 8, we see a powerful illustration of Jesus's mercy when He encounters a woman caught in adultery. The accusers bring her to Jesus, but instead of condemning her, Jesus offers her forgiveness, saying, "Neither do I condemn thee; go and sin no more" (John 8:11). This episode illustrates that Jesus came not to condemn sinners but to save them (John 3:17). His mercy is offered to all who recognize their need for grace and do not hide behind self-righteousness. As a sovereign grace teaching, this act underscores that while we are all deserving of judgment, Jesus's sacrificial death paid the penalty for our sins, offering true and lasting forgiveness to those who believe in Him.
