One has physically act upon what Jesus had said until they are able to get the Father to reveal Himself!
James 2:17 > "Faith without action is useless"
The only thing that involves sacrifice on one's behalf that Jesus mentioned was to give to the poor and needy. Jesus sacrificed his life both physically and symbolically for all the sins of humanity therefor all people need to sacrifice for one another in order to make it to the Father! This is also validated in Romans (written by Paul the Apostle) where one will be judged based on their pursuit of Righteousness and Good Works instead of their sins. Why? Jesus already paid for the sins of humanity therefor people will be judged by how treat one another by their pursuits of Righteousness and Good Works!
No one ever claimed that they made it to the Father just by claiming that they were "Saved!" Everything has to match the Bible 100% and to match Scripture exactly one is required to go through Jesus to get to the Father, correct? Salvation is the Free but the path that leads to that Salvation not Free!
Jesus would have said this exactly but instead Jesus said that few will make it through the narrow gate (Mathew 7:13 ~14) and Jesus was / is God in the living flesh and blood according to the Book of John. This would mean that one would be required to physically do something to get to the Father in order to become "Saved." The only thing that Jesus really asked of His followers that involved physical sacrifice was to give to the poor and needy!
