False, we can never be as Christ, which is why He is our Savior.
That is not what the scriptures say.
Romans 8:29 For those God foreknew he also predestined to be conformed to the image of his Son, that he might be the firstborn among many brothers and sisters.
1 Corinthians 15:49
And just as we have borne the image of the earthly man, so shall we bear the image of the heavenly man.
2 Corinthians 3:18
And we all, who with unveiled faces contemplate the Lord's glory, are being transformed into his image with ever-increasing glory, which comes from the Lord, who is the Spirit.
Philippians 3:21
who, by the power that enables him to bring everything under his control, will transform our lowly bodies so that they will be like his glorious body.
Colossians 3:10
and have put on the new self, which is being renewed in knowledge in the image of its Creator.
Romans 8:29 For those God foreknew he also predestined to be conformed to the image of his Son, that he might be the firstborn among many brothers and sisters.
Hebrews 2:11 Both the one who makes people holy and those who are made holy are of the same family. So Jesus is not ashamed to call them brothers and sisters.
He is who the Father looks upon when He looks upon a believer, we are filled with sin in our flesh.
We are washed. We are to offer our bodies as living sacrifices.
Hebrews 10:22 let us draw near to God with a sincere heart and with the full assurance that faith brings, having our hearts sprinkled to cleanse us from a guilty conscience and having our bodies washed with pure water.
Romans 12:1 Therefore, I urge you, brothers and sisters, in view of God's mercy, to offer your bodies as a living sacrifice, holy and pleasing to God--this is your true and proper worship.
You either trust He did it all for you, or you flail in your flesh without Him.
All your works are as filthy rags.
It is never ever wrong in any way to obey God. God does not tell us our righteous acts are as filthy rags when we do what He says.
God was speaking to the Jews WHO WOULD NOT STOP SINNING. For instance, in the old law, the Jews would sin, then they had to give a sin offering as a righteous act, they had to give sin offerings just to worship God. God did not like it that they would sin then give a sin offering and not really be sorry for their sins.
Your false teachers taught you wrong about the filthy rags scripture.
Your righteous act of FAITH in Jesus is a filthy rag if you do not OBEY HIM.
