Q. I believe your teaching that Jesus’ payment for my sins covers all of my sins from birth to death. Why do some teachers teach that the Lord’s death only covers one’s past sins, and we are personally responsible for our future ones?
A. People who teach that only our pre-salvation sins are covered don’t fully comprehend what happened at the cross. The Bible says His death was a once-for-all-time sacrifice for sin that has made perfect forever those who are being made Holy (Hebrews 10:12-14). “Once-for-all-time” means His death covered every sin from the beginning of time until the end. “Made perfect forever” means every sin of our lifetime was paid for with His blood. “Made holy” means we are sanctified, set apart from profane things and dedicated to God. Colossians 2:13-14 confirms this.
This is why Ephesians 1:13-14, 2 Cor. 1:21-22 and other places can promise that our salvation is guaranteed when we believe. If any of our future sins could cause our salvation to be revoked, Paul could not have made that promise.
And Finally, John called Jesus the Lamb of God who takes away the sin of the world (John 1:29). From the cross Jesus said, “It is finished” and died (John 19:30). The job He came to do was accomplished. The Lamb of God had taken away the sin of the world. All that’s left for us to do is believe it.
“For I am convinced that neither death nor life, neither angels nor demons, neither the present nor the future, nor any powers, neither height nor depth, nor anything else in all creation, will be able to separate us from the love of God that is in Christ Jesus our Lord” (Romans 8:38-39).
