Agreed, but only through faith in Christ.
A deathbed confession simply places the believer in fellowship with God. Such a person isn’t getting away with anything, because they missed out on a lifetime of opportunity to be in position for God the Holy Spirit to further sanctify them. They also missed out on many an opportunity to perform good works while in faith in Christ, which are counted at the bema seat for the issuance of rewards by our Lord and Savior Christ Jesus.
Some have said that those rewards, which were predestined from eternity past, when left unclaimed by sin, merely result in an eternal memorial of our foolishness in accepting sin instead of Him.
The Cross resolved the issue of sin in the relationship of God with mankind. Good and evil as consequences of sin, still must be dealt with in time.
We appear to be pretty well on the same page, here.
I shudder, though, at the heresy of predestination. While God knows what we’re up to and will be up to, it’s still our call in the here and now.
Of our own free will do we accept Him or reject Him.
