Two things Jesus’ sacrifice at the cross never did despite what you may have heard:
1. Jesus did not live a perfect sinless life and be crucified so that you wouldn’t have to follow the law. Romans 6:23 tells us the wages of sin is death. This means we must still keep the law of Christ or face eternal damnation (the second death).
2. Jesus did not take your place on the cross so that you would never have to die. While it is unlikely you will be put to death by crucifixion, you or I can still be put to death for our faith. In fact in Revelation Jesus warns us to be faithful unto death. See also John 15:20. This means as Christians that trials, temptations, torture, and even death (physical death) are still real possibilities.
