If I didn't understand the doctrine, I couldn't obey God.I don't think you understand the process of salvation....for one.
You have been provided with plenty of scriptures to make the truth clear.
You just do not want to believe the truth.
And that is pretty much my final word....because I do not like repeating myself.
1 Hear the words of life.
2 Repent of sin and get baptized in the name of Jesus Christ for the remission of my past sins.
2a At the same time be sanctified and justified by the atoning blood of my Savior.
2b And crucify/destroy the "flesh" with its vile affections and lusts, and be raised with Christ to walk in newness of life/rebirth !
Now I continue in the last step...enduring faithfully until the end.
Did I miss anything ?
BTW, the truth can make you free from sinning. (John 8:32-34)
