But this is not the right response to what I had said. I did not contend with this idea.
The question is: Did Jesus die to save us in our sins, or to save us from Sin?
Both.
Then what sense is there in telling people to repent of their sins?
Repentance shows that you are truly sorry for your sin and have authentically accepted the gift of salvation. It shows you want to live in a way that is pleasing to Him out of a love response for the salvation that has been procured and assured.
What sense is there in asking God for forgiveness if we have already been saved from Sin?
Our salvation is not conditional upon our repentance nor how much we grovel and plead at the feet of Christ. That is trying to earn a free gift. Salvation is a gift, not a reward for good works.
Many Adventists just don't sem to grasp this.
What about faith? Doesn't that matter? Can one be justified without it?
Justification is an act that takes place completely outside the individual, an accomplished fact not conditional upon anything but acceptance.
Faith is the trust we have in Christ's righteousness and His merits. Even though we may 'feel' lost or question or doubt our salvation at times, we have faith that Christ has indeed accomplished what he has said He will accomplish. Thus, justification by 'faith'.
What aspect of sin are you referring to here, the guilt, power, nature of it, or all three?
The condemnation, power and guilt of sin was all vanquished at the cross. The sinful nature is changed when we are glorified.
