Actually, you have to take God at His word and believe that he will bring about what He has promised. He’ll see you get through any necessary steps.
“Philippians 1:6 being confident of this, that he who began a good work in you will carry it on to completion until the day of Christ Jesus.”
Yes indeed. HE starts and finishes the good work in you. Salvation is, from beginning to end, in HIS hands. He doesn’t do it through a false gospel. All those God the Father teaches will come to Christ and be saved. (John 6:45). Every single person God purposed to save will be saved. Every single man given to Christ by the Father will come to Christ and be saved (John 6:37).
