Some people will use Matthew 7:21-23 to prove that a person must do the will of the Father and if they work any iniquity then they can lose their Salvation. However that's not what the verse is saying, the verse points out that those who are workers of iniquity are those who are relying on their works for Salvation at verse 22. That's why God calls them workers of iniquity, because they rely on their works for Salvation not by the Faith of Jesus Christ. Ephesians 2:8-9 points out that we are saved by Grace through Faith believing on Christ and not by works.
Another reason why the Bible says in Matthew 7:21 that those who do the will of the Father can go to Heaven is very simple, the will of the Father is to believe on Christ for Salvation rather than good works (in this Church Age).
