I agree, but do you understand what rejecting Christ is?
It is the rejecting of the faith Christ had which hits its mark.
If one rejects believing in love, mercy, justice, truth,..., and instead continually chooses to believe in missing the mark (sin), then that persons faith in Christ is less than one who has never heard of the Way of Christ.
That individual will receive more lashes than the one who never heard of the Way to target. (Luke 12:46-48)
Luke 12:46 The lord of that servant will come in a day when he looketh not for him, and at an hour when he is not aware, and will cut him in sunder, and will appoint him his portion with the unbelievers.47 And that servant, which knew his lord's will, and prepared not himself, neither did according to his will, shall be beaten with many stripes.
48 But he that knew not, and did commit things worthy of stripes, shall be beaten with few stripes. For unto whomsoever much is given, of him shall be much required: and to whom men have committed much, of him they will ask the more.
