Out of ourselves, we will never reach heaven or the path to the father. Only if we accepted that Jesus died in our place, conquer death and went back to heaven to sit on the right-hand side of the father from where He intercedes for us.

Romans 8: 33 Who shall bring a charge against God’s elect? It is God who justifies. 34 Who is he who condemns? It is Christ who died, and furthermore is also risen, who is even at the right hand of God, who also makes intercession for us.
God bless!
