The doom for you is rejection of God's 10 commandment law.When you say “you don’t want to be obedient to God’s will,” you’re assuming a spiritual posture that Scripture never allows you to diagnose in another believer’s heart.
Jesus forbids that move in Matthew 7 — you can judge fruit, but you cannot judge motives, because motives belong to God alone (1 Cor 4:5).
And when you say “heaven for you is eternal murder, adultery, worshiping idols,” that’s not exhortation — that’s accusation, and Revelation 12 calls that the dragon’s vocabulary, not the Spirit’s.
The Spirit convicts of sin, yes, but He does it by exposing actual disobedience, not by assigning imaginary wickedness to someone’s future state.
You’re right that human nature resists God (Rom 8:7), and you’re right that obedience is only possible through the Spirit (Rom 8:13), but the way you’re speaking right now is not the Spirit’s method.
The Spirit produces gentleness, patience, and truth — not prophetic doom aimed at a brother.
All through the OT God's Spirit led His prophets to condemn the wicked in the hopes they would repent.
The choice is your to follow Jesus or continual life lived in rebellion against Him.
