Can we ransom ourselves? Can you save yourself through your own deeds?

Re: Hadith Bukhari 76:546; 76:547

This is what the LORD says: When I came, why was there no one? When I called, why was there no one to answer? Was my arm too short to ransom you? Do I lack the strength to rescue you? Isaiah 50:2

"I will ransom them from the power of the grave; I will redeem them from death. Where, O death, are your plagues? Where, O grave, is your destruction? Hosea 13:14

For even the Son of Man did not come to be served, but to serve, and to give his life as a ransom for many." Mark 10:45

This is good, and pleases God our Savior, who wants all men to be saved and to come to a knowledge of the truth. For there is one God and one mediator between God and men, the man Christ Jesus, who gave himself as a ransom for all men--the testimony given in its proper time. 1 Timothy 2:3-6

How much more, then, will the blood of Christ, who through the eternal Spirit offered himself unblemished to God, cleanse our consciences from acts that lead to death, so that we may serve the living God! For this reason Christ is the mediator of a new covenant, that those who are called may receive the promised eternal inheritance--now that he has died as a ransom to set them free from the sins committed under the first covenant. Hebrews 9:14-15

For it is by grace you have been saved, through faith--and this not from yourselves, it is the gift of God. Ephesians 2:8
