How do we know Christ's atonement is effective for sinners?
Answered in 2 sources
Christ's atonement is effective because He was both truly God and truly man, satisfying divine justice with His sacrifice.
The effectiveness of Christ's atonement lies in His dual nature as both God and man. As explained in the sermon, only someone who is fully God can offer a perfect sacrifice, yet only a man can represent mankind. Thus, Christ, as the God-man, uniquely qualifies to be the mediator who reconciles us to God. This is supported by verses like 1 Peter 3:18, which emphasizes that He suffered for our sins. Additionally, His one-time sacrifice is sufficient, establishing a permanent solution for our sinfulness, as reiterated in Hebrews 10:14, which states that by one offering, He has perfected forever those who are sanctified.
