People either accept or reject Jesus and are either good or bad, roughly speaking. So the four possible categories are (1) good people accepting Jesus, (2) bad people accepting Jesus, (3) good people rejecting Jesus, and (4) bad people rejecting Jesus. Obviously, you should want to belong in the first and not the last category. How about the middle two? I see that a bad person accepting Jesus can easily be saved if he would just repent of his sins and ask for God's forgiveness. But a good person rejecting Jesus risks being rejected by him before the Father, as the Gospel tells us. Naturally, the Lord alone knows why he is not being accepted. Nevertheless, knowingly rejecting Christ will definitely have serious consequences.
