If we are to be built up in the image and likeness of Christ, then we must move beyond repenting of sins. We should seek to find the "godly sorrow" which works towards salvation. Repentance from sin is a function for those bound to the law and to a schoolmaster.
I seriously disagree with you. Repentant faith is an absolute must for the salvation doctrine .
Here are some examples:
So watch what you do! “If your brother sins, rebuke him, and if he repents, forgive him. (Luke 17:3)
As the Lord’s servant, you must not quarrel. You must be kind toward all, a good and patient teacher, who is gentle as you correct your opponents, for it may be that God will give them the opportunity to repent and come to know the truth. (2 Timothy 2:24-25)
The apostles left and started telling everyone to turn to God. (Mark 6:12)
Peter said to them, “Each one of you must turn away from your sins and be baptized in the name of Jesus Christ, so that your sins will be forgiven; and you will receive God’s gift, the Holy Spirit. (Acts 2:38)
I told you my sins, and I am sorry for them. (Psalm 38:18)
Luke 3:3 ►
Verse (Click for Chapter)
New International Version
He went into all the country around the Jordan, preaching a baptism of repentance for the forgiveness of sins.
New Living Translation
Then John went from place to place on both sides of the Jordan River, preaching that people should be baptized to show that they had repented of their sins and turned to God to be forgiven.
Matthew 3:2 ►
"Repent, for the kingdom of heaven has come near."
Therefore no repentance no forgiveness. And if no forgiveness then NO SALVATION.
We have a sin nature , even after coming to Christ and it's very likely we will sin. It becomes very important to quickly acknowledge and repent each time we we sin . Yes we must go past this stage into greater obedience. But must also repent each time it occurs.
