2 Corinthians 5:21 (NIV)  

God made him who had no sin to be sin for us, so that in him we might become the righteousness of God.  

Jesus Christ our Lord lived the perfect and blameless life that we cannot live and died on a death that we should have died. On that cross, the Son of God, who knew no sin, became sin in our behalf. He bore the wrath of God and the condemnation for our sins and on that cross He drank the hell that we deserve. So that those who will believe in His glorious Name, the Name above all Name, will have the forgiveness of their sins and eternal life with Him. 

Acts 4:12

 "Salvation is found in no one else, for there is no other name under heaven given to mankind by which we must be saved." 

 John 14:6

Jesus answered, "I am the way and the truth and the life. No one comes to the Father    except through me.
