The Pharisees called Christianity a cult tooThis is just a silly rant which actually goes against what is in the Bible. Looks like some unbelieving "scholars" got to you. All the cults deny the reality of an eternal Hell.
Matthew 23
29 Woe unto you, scribes and Pharisees, hypocrites! because ye build the tombs of the prophets, and garnish the sepulchres of the righteous,
30 And say, If we had been in the days of our fathers, we would not have been partakers with them in the blood of the prophets.
31 Wherefore ye be witnesses unto yourselves, that ye are the children of them which killed the prophets.
1 Corinthians 15
21 For since by man came death, by man came also the resurrection of the dead.
22 For as in Adam all die, even so in Christ shall all be made alive.
23 But every man in his own order: Christ the firstfruits; afterward they that are Christ's at his coming.
24 Then cometh the end, when he shall have delivered up the kingdom to God, even the Father; when he shall have put down all rule and all authority and power.
25 For he must reign, till he hath put all enemies under his feet.
26 The last enemy that shall be destroyed is death.
27 For he hath put all things under his feet. But when he saith all things are put under him, it is manifest that he is excepted, which did put all things under him.
28 And when all things shall be subdued unto him, then shall the Son also himself be subject unto him that put all things under him, that God may be all in all.
