How do we know Christ's sacrifice is enough for our sins?

The sufficiency of Christ's sacrifice is evidenced in Hebrews 10:4, where it states that the blood of bulls and goats cannot take away sins, indicating that only a perfect sacrifice would suffice. Jesus, as the God-man, provided that perfect offering, fulfilling the law's demands and appeasing God's justice. His death was a one-time event that secured eternal redemption for His people. The fact that He rose from the dead demonstrates God's acceptance of His sacrifice, confirming that He has indeed dealt with our sins once and for all, as noted in Colossians 1:20, where it says He made peace through the blood of His cross.
