How do we know that Christ obtained mercy for us?

Christ obtained mercy for His people by taking on our sins and suffering the penalty for them on the cross. In Ephesians 2:4-5, it is stated, 'But God, who is rich in mercy, for His great love wherewith He loved us, even when we were dead in sins, hath quickened us together with Christ.' This clearly demonstrates that through His death and resurrection, He fulfilled the requirements of justice, allowing God to extend mercy to sinners without compromising His holiness. This obtained mercy is available to all who call upon Him and recognize their need for grace.
