How do we know salvation is accomplished in Christ?

The assertion that salvation is accomplished in Christ is rooted in His fulfillment of every aspect of the Law of God. According to the sermon, Christ did not come merely to assist in achieving salvation but to accomplish it entirely by His obedience, culminating in His sacrificial death. Romans 1:4 states that He was 'declared to be the Son of God with power by the resurrection from the dead,' providing evidence of His successful atonement for sin. Through His death, He paid the penalty for sin, and through His resurrection, He proved His victory over death, granting believers the assurance of salvation. This doctrinal foundation corresponds with the sovereign grace understanding that our salvation is wholly of the Lord and is not based on human effort.
