If one were to hold to your stated view, "Christ said all is finished that accomplished the saving of all for whom He died" then He saved everyone, no one is lost. That would make you a universalist, are you saying that you are?
According to scripture, who did Christ die for?
Rom 5:6 For while we were still helpless, at the right time Christ died for the ungodly.
Rom 5:8 But God demonstrates His own love toward us, in that while we were yet sinners, Christ died for us.
1Ti 2:5 For there is one God, and one mediator also between God and men, the man Christ Jesus,
1Ti 2:6 who gave Himself as a ransom for all, the testimony given at the proper time.
BF no one was saved by His death. Christ was the appeasing sacrifice that reconciled the world to God. {1John 2:2} God sent His son into the world as a savior, {John 3:17} because the desire of His heart was that all should be saved. {1Timothy 2:3-4}
The world was reconciled to God through His death. {Romans 5:10 a} But only those that freely trust in the risen Christ will be saved. {Romans 5:10 b}
Christ died so that all could be saved {John 3:17} We see the relationship between God and man clearly in the following verse from Paul {2Corinthians 5:18-21} God, through Christ, reconciled the world to Himself thus making it possible for man to be reconciled to God. Man must submit to God's terms of mercy, faith in His risen son. God has removed all the obstacles to reconciliation which existed on his part. Now it remains that man should lay aside his hostility, abandon his sins, embrace the terms of mercy, and become in fact reconciled to God.
BF you keep saying that it was His death that saves while the bible says it is His life. You want to trust in a dead man and I trust in the risen Christ.
