Jesus guarantees us salvation:

We are righteous by faith and not works:

Romans 4 “To the one who does not work but trust God who justifies the ungodly God will credit righteousness—for us who believe in him who raised Jesus our Lord from the dead. 25 He was delivered over to death for our sins and was raised to life for our justification.”

Now that we are righteous by faith, we will surely be saved from the wrath to come.

Romans 5 “Therefore, since we have been justified through faith, we have peace with God through our Lord Jesus Christ,…. 9 Since we have now been justified by his blood, how much more shall we be saved from God’s wrath through him! “

There is no wrath for the believer:

1 Thessalonians 5 “9 For God did not appoint us to suffer wrath but to receive salvation through our Lord Jesus Christ.”

Jesus will not refer to our sins anymore because He already took it away on the cross. But He will come to bring salvation!

Hebrews 9 ” 27 Just as people are destined to die once, and after that to face judgment, 28 so Christ was sacrificed once to take away the sins of many; and he will appear a second time, not to bear sin, but to bring salvation to those who are waiting for him.”
