Of course not. My works and all mere human works are futile.
Only Our Lord had the ability to atone.
The crux here is that we have free will and must attend to our own salvation to join into what He did. He paid His debt and opened the Gate - we must make our own way through the Gate.
It is not that difficult a concept.
In light of this, why did Christ have to die for our sins?
What debt did Jesus have to pay that was "his debt"? Do you understand that he paid OUR debt? He not only opened the gate but he is the DOOR, we go through him to get to Heaven. We receive him, believing on him as our savior, trusting in him who paid our sin debt and THAT is how we go through the door. He said, "I am the way, the truth and the life, no man comes to the Father but by me.". You know the saying, "It's my way or the highway"? Well the Father says his way is through Jesus who is THE only way. The way we "make our way through the gate" is by faith. BY grace THROUGH faith.
