Scripture tells us (more than once) that the offering of the Lord Jesus Christ is sufficient to take away the sin of the world ...
John 1:29 The next day John seeth Jesus coming unto him, and saith, Behold the Lamb of God, which taketh away the sin of the world.
John 3:16-17 For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life. For God sent not his Son into the world to condemn the world; but that the world through him might be saved.
2 Corinthians 5:19 To wit, that God was in Christ, reconciling the world unto himself, not imputing their trespasses unto them; and hath committed unto us the word of reconciliation.
1 John 2:2 And he is the propitiation for our sins: and not for ours only, but also for the sins of the whole world.
Scripture tells us when a man or woman is justified (i.e. when God imputes righteousness):
Romans 4:
20 He [Abraham] staggered not at the promise of God through unbelief; but was strong in faith, giving glory to God;
21 And being fully persuaded that, what he [God] had promised, he [God] was able also to perform.
22 And therefore it was imputed to him for righteousness.
23 Now it was not written for his sake alone, that it [righteousness] was imputed to him;
24 But for us also, to whom it [righteousness] shall be imputed, if we believe on him that raised up Jesus our Lord from the dead;
25 Who was delivered for our offences, and was raised again for our justification.
5:1 Therefore being justified by faith, we have peace with God through our Lord Jesus Christ
