You err concerning Matt 7:21-23. Jesus doesn't tell them to depart for their actions, but because He never knew them. This is why I asked you what it means to be in Christ.
Can you tell me in your own words what it means to be...in Christ?
Here's a paper of mine on this very subject "in Christ" posted previously and elsewhere
"In Christ": What does it really mean?
The words “in Christ” and similar, i.e.; “in Jesus Christ”, “in Christ Jesus”, “in him’, are used ad nauseam within the Christian world with hardly anyone ever giving any thought whatsoever as to what the words really mean or entail, thus relegating them to nothing more than Christian “buzz words” that sound good and Christian-like.
So what do these words really mean? What does it mean to be “in Christ” and how does one get “in Christ” or into Christ? Is there a specific way stated in the bible? Are there unique benefits for being “in Christ” once one has achieved that state of being “in him”? Are there benefits available to those not being “in Christ”? Can you receive spiritual blessings without being “in Christ”?
These are logical questions that should be asked or considered when one sees or uses these or similar words inferring the same.
There are 146 references in the New Testament (may not be all inclusive, but close if not) using these exact or similar words as those mentioned above. If mentioned that frequently and to that extent, it must be of great importance, so likewise, all should render like importance to these words when using them, clearly understanding what they truly mean and entail.
Consider the suffix “ian” attached to the word “Christ” to become the word Christian; what does "ian" attached to the end a word mean or indicate? One of its meanings is 'from or belonging to'. As it pertains to Christ, it indicates that a Christian is from or belonging to, or in other words, owned by Christ! It should be noted too that the word “Christian” doesn’t mean a believer in or follower of Christ, but rather really means owned by Christ. So, you could be a believer in and follower of Jesus, practice some form of “Christian” religious worship, be devout, moral, etc. etc, but not be owned by Him, not “in him”.
Note that the bible says the following:
1 Cor 6:20 "For ye are bought with a price:"
Acts 20:28 “Take heed therefore unto yourselves, and to all the flock, over the which the Holy Ghost hath made you overseers, to feed the church of God, which he hath purchased with his own blood."
The above clearly states that Christ purchased or bought the church with His own blood, so it's clear that Christians, those owned by Christ, those that are part of his body (the church), have been bought and paid for by his blood which was the price he paid for them who are now “in him”. Therefore, those that are “in” the church are His, and are “in him”.
What are some of the benefits that being owned by or “in Christ” bestowed upon you that are unable to be conferred in any other way according to scripture?
• Be saved, receive redemption, have your sins remitted and added to the Lord’s body which is the church
• Be buried/planted with Him in the likeness of his death thus enabling like resurrection
• Put on Christ and become a Christian and child of God
• Receive the Holy Spirit, spiritual gifts, blessings, have hope, and be made alive in Him
So, how do you become owned by, “in Christ”, and part of the church? The fact of the matter is, there is one specific way mentioned in the bible as to what one must do to be “in Christ” as well as benefits for being “in him” that can only be realized thereby: by baptism.
Rom 6:3 “Know ye not, that so many of us as were baptized into Jesus Christ were baptized into his death”?
Gal 3:26/27 “For ye are all the children of God by faith in Christ Jesus. For as many of you as have been baptized into Christ have put on Christ”.
1st Cor 12:13 “For by one Spirit are we all baptized into one body, whether we be Jews or Gentiles, whether we be bond or free; and have been all made to drink into one Spirit.
Rom 6:4 “Therefore we are buried with him by baptism into death: that like as Christ was raised up from the dead by the glory of the Father, even so we also should walk in newness of life”.
Col 2:12 “Buried with him in baptism, wherein also ye are risen with him through the faith of the operation of God, who hath raised him from the dead”.
Rom 6:5 “For if we have been planted together in the likeness of his death, we shall be also in the likeness of his resurrection”:
Acts 2:38 “Then Peter said unto them, Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost”. 41 “Then they that gladly received his word were baptized: and the same day there were added unto them about three thousand souls”. 47 “Praising God, and having favour with all the people. And the Lord added to the church daily such as should be saved.”
• Christ’s body is the church of which He is the head (Col 1:18, Eph 5:23);
• You become part of the church by becoming a part of His body. You become part of His body by being baptized into it.
• In it (His body, the church), you obtain spiritual blessings (Eph 1:3).
• Are you really a Christian without being part of His body, the church, which you are added to upon being baptized (Acts 2:41, 47)?
• If you’re not buried with Him through baptism, can you then still be raised with Him?
