I am prepared to challenge you on water baptism-good works-confessing sins-commandment keeping and "etc. "What does it mean to be perfect?" Sinless?
Jesus is Salvation.
Nothing else.
So, if a person is teaching that "water baptism, and good works, and Penance, commandment keeping, and confessing sins" are a part of Salvation, then they are not understanding the Cross of Christ that is God's Gift of Salvation.
Therefore,.... all These self efforts that you listed...
The Self effort of getting in the Water
The Self effort of confessing sin
The Self effort of obsessing on commandment keeping,
YOU do those, as your idea of Discipleship... Whereas... Christ on the Cross completed your Salvation, John 3:16... 2nd Cortinthians 5:19... John 3:17......Romans 4:8...... before you were born.
Christ died for the sin of the world, in the Foreknowledge of God, before Lucifer became Satan, and before Eve trusted a talking serpent.
JESUS is Salvation.... or as Paul teaches that we preach this as ..."Christ Crucified".
Do not ADD to the Cross, personal self effort,., as this Denies the Cross.
Its really just one simple understanding that can free you ...
Recognize that SALVATiON is What God did for us, as Christ on the Cross 2000 yrs ago.
And, Discipleship is what we do AFTER we have received from God, what Christ has completed for us on the Cross.
Salvation and Discipleship, are not the same.
