The apostle John uses hilasmos (Strong's #2434) to describe Jesus Christ. In I John 2:2, John writes, “And He [Christ] is the propitiation [hilasmos] for our sins,” which is to say that His sacrifice satisfied the legal requirements of God's law and holiness for the punishment of sin. Therefore, through the ultimate act of mercy and grace, Christ became our propitiation and our Advocate (I John 4:10).
